Our optical power meter kits consist of a console, a C-series photodiode or thermal power sensor, and a post mounting assembly. Except for the PM120VA, which includes the PM100A analog power meter console, the sensor in each kit is paired with either a PM100D digital or PM400 touchscreen digital power meter console. For a full list of available kits, see Table 1.1.

All three consoles have a USB 2.0 connection that allows them to be controlled remotely using a PC with the Optical Power Meter software package installed (see the Software tab for details).

PM100A Analog Console
Suitable for both absolute and relative power measurements, the PM100A analog power meter console features an analog needle display and a supplemental LCD screen. The analog needle is ideal for relative power measurements and for watching small power fluctuations. The PM100A is compatible with all C-Series photodiode sensors and thermal sensors; it is not compatible with our pyroelectric energy sensors. The PM120VA power meter kit includes the PM100A console and power cables, an S120VC sensor, and a USB flash drive with the software package preloaded. For more information on the PM100A analog console features, see the Specs and Display tabs or visit the full web presentation.

PM100D Digital Console
The PM100D digital power and energy meter console features a menu-driven control panel, 4" backlit display, and SD card slot for storing data. Measurements screens include a numeric readout useful for standard power and energy readings, a simulated analog needle, graphs of power measurements over time, and a statistics view. Additionally, the PM100D console has a tuning mode that provides audio feedback for use when the detector is not within visual range. See the PM100D Display tab for more information. The console is compatible with all our C-Series sensors for power or energy measurements, including our pyroelectric energy sensors, and includes a USB flash drive with the software package preloaded. For more information on the PM100D digital console features, see the Specs and Display tabs or visit the full web presentation.

PM400 Touchscreen Digital Console
The PM400 touchscreen digital power and energy meter console features a 4.3" display with multi-touch technology. Capacitive buttons on the front of the unit enable fast access to set the source wavelength or spectrum, a delta mode that shows the change in power from a user-selected set point, the zeroing function, and device main menu. In addition to pre-programming source wavelengths or spectra for calibrating measurements, users can enter and save up to twelve attenuation values or data files to correct for effects that external devices (such as filters or beamsplitters) may have on the power measurement.

A 14-pin auxiliary input allows users to connect their own humidity and temperature sensors as well as access four programmable I/O ports for controlling shutters, interlock devices, laser warning lights, and other common lab devices (see the Pin Diagrams tab for pin descriptions). Alternatively, a 2.5 mm stereo (3P) jack accepts the TSP-TH thermistor temperature probe. Like the PM100D, this console is compatible with all our C-Series sensors. For more information on the PM400 touchscreen digital console features, see the Specs and Display tabs or visit the full web presentation.

Additional Power Meter and Sensor Options
The power meter consoles and sensors in these kits can also be purchased individually. Additionally, Thorlabs offers self-contained wireless power meters, designed for both handheld operation and remote control via Bluetooth or USB, and compact USB power meters, designed to be operated via software control on a PC.

Recalibration Services
Recalibration services are available for our photodiode and thermal power meter sensors and consoles. We recommend recalibrating your Thorlabs sensor and console as a pair; however, each may be recalibrated individually. All of the sensors on this page come with a manufacturer calibration by default, but we also offer an ISO17025 accredited calibration for some items. For more information on calibration options, please see the Recalibration tab or the calibration sections at the bottom of this page.

    Optical Power Monitor GUI Software for Touchscreen, Handheld, and USB-Interface Power Meters

    Features

    • Operate up to Eight Power Meters Simultaneously
    • Record and Analyze Measurements in Real Time
    • Intuitive Analog Display and Graphing Modes
    • Configurable Long-Term Data Logging
    • Also Supports Position Measurements with Thermal Position & Power Sensors

    The Optical Power Monitor software GUI enables seamless control of up to eight power meters that are connected via USB, RS232, or Bluetooth® wireless technologya. The latest software, firmware, drivers, and utilities for these power meters can be downloaded here.

    Multiple data measurement and analysis functions are integrated into the GUI package. The interface offers a user-friendly design with minimal use of color and low brightness that is ideal use in dark lab environments while wearing laser safety glasses. Measured data can be displayed in real time as a simulated analog needle, digital values, line graph, or bar graph. Continuously logged and short-term measurements can be recorded for data viewing and analysis at a later point. A built-in statistics mode analyzes measured data and continuously updates to reflect new measurements within the pre-determined measurement period. Beam position measurements are also supported when used with our thermal position & power sensors.

    The Optical Power Monitor software package installs the GUI, which then can be used to control the touchscreen, handheld, or USB-interface power meters. Firmware updates for supported power meters are also available. Programming examples and drivers for interfacing with our power and energy meter consoles using LabVIEW, C/C++, Visual C#, and Python are installed with the software; refer to the manual for details.

    Please note that the Optical Power Monitor Software uses different drivers than the Power Meter Utilities Software and Thorlabs recommends using the new driver TLPM.dll. For users who wish to use the legacy Power Meter Software or use custom software designed using the older PM100D.dll driver, a Power Meter Driver Switcher program is included for easy swapping of the installed driver between the two versions.

    a. The PM61 Series, PM160, PM160T, and PM160T-HP power meters are equipped with Bluetooth® connections.

    Pulsed Laser Emission: Power and Energy Calculations

    Determining whether emission from a pulsed laser is compatible with a device or application can require referencing parameters that are not supplied by the laser's manufacturer. When this is the case, the necessary parameters can typically be calculated from the available information. Calculating peak pulse power, average power, pulse energy, and related parameters can be necessary to achieve desired outcomes including:

    • Protecting biological samples from harm.
    • Measuring the pulsed laser emission without damaging photodetectors and other sensors.
    • Exciting fluorescence and non-linear effects in materials.

    Pulsed laser radiation parameters are illustrated in Figure 170A and described in Table 170B. For quick reference, a list of equations is provided below. The document available for download provides this information, as well as an introduction to pulsed laser emission, an overview of relationships among the different parameters, and guidance for applying the calculations. 

     

    Equations:

    Period and repetition rate are reciprocal:    and 
    Pulse energy calculated from average power:       
    Average power calculated from pulse energy:        
    Peak pulse power estimated from pulse energy:            

    Peak power and average power calculated from each other:
      and
    Peak power calculated from average power and duty cycle*:
    *Duty cycle () is the fraction of time during which there is laser pulse emission.

    Click to Enlarge

    Figure 170A  Parameters used to describe pulsed laser emission are indicated in this plot and described in Table 170B. Pulse energy (E) is the shaded area under the pulse curve. Pulse energy is, equivalently, the area of the diagonally hashed region. 

    Table 170B  Pulse Parameters
    Parameter Symbol Units Description
    Pulse Energy E Joules [J] A measure of one pulse's total emission, which is the only light emitted by the laser over the entire period. The pulse energy equals the shaded area, which is equivalent to the area covered by diagonal hash marks.
    Period Δt  Seconds [s]  The amount of time between the start of one pulse and the start of the next.
    Average Power Pavg Watts [W] The height on the optical power axis, if the energy emitted by the pulse were uniformly spread over the entire period.
    Instantaneous Power P Watts [W] The optical power at a single, specific point in time.
    Peak Power Ppeak Watts [W] The maximum instantaneous optical power output by the laser.
    Pulse Width Seconds [s] A measure of the time between the beginning and end of the pulse, typically based on the full width half maximum (FWHM) of the pulse shape. Also called pulse duration.
    Repetition Rate frep Hertz [Hz] The frequency with which pulses are emitted. Equal to the reciprocal of the period.

    Example Calculation:

    Is it safe to use a detector with a specified maximum peak optical input power of 75 mW to measure the following pulsed laser emission?

    • Average Power: 1 mW
    • Repetition Rate: 85 MHz
    • Pulse Width: 10 fs

    The energy per pulse:

    seems low, but the peak pulse power is:

    It is not safe to use the detector to measure this pulsed laser emission, since the peak power of the pulses is >5 orders of magnitude higher than the detector's maximum peak optical input power.

    Thorlabs offers a wide selection of power and energy meter consoles and interfaces for operating our power and energy sensors. Key specifications of all of our power meter consoles and interfaces are presented in this tab to help you decide which device is best for your application. We also offer self-contained wireless power meters and compact USB power meters.

    When used with our C-series sensors, Thorlabs' power meter consoles and interfaces recognize the type of connected sensor and measure the current or voltage as appropriate. Our C-series sensors have responsivity calibration data stored in their connectors. The console will read out the responsivity value for the user-entered wavelength and calculate a power or energy reading.

    • Photodiode sensors deliver a current that depends on the input optical power and the wavelength. The current is fed into a transimpedance amplifier, which outputs a voltage proportional to the input current. The photodiode's responsivity is wavelength dependent, so the correct wavelength must be entered into the console for an accurate power reading. The console reads out the responsivity for this wavelength from the connected sensor and calculates the optical power from the measured photocurrent.
    • Thermal sensors deliver a voltage proportional to the input optical power. Based on the measured sensor output voltage and the sensor's responsivity, the console will calculate the incident optical power.
    • Energy sensors are based on the pyroelectric effect. They deliver a voltage peak proportional to the pulse energy. If an energy sensor is recognized, the console will use a peak voltage detector and the pulse energy will be calculated from the sensor's responsivity.

    The consoles and interfaces are also capable of providing a readout of the current or voltage delivered by the sensor. Select models also feature an analog output.

    • These power meter interfaces do not have a built-in monitor, so all data must be displayed through a PC running the Optical Power Monitor Software.

    Recalibration Services
    Thorlabs offers two types of recalibration services in-house for our power and energy meter electronics and photodiode power sensors: ISO17025 accredited calibrations and manufacturer calibrations. Only the manufacturer calibration is available for the NS170C microscope slide peak power sensor, our thermal power sensors, and our pyroelectric energy sensors. All new products are delivered with a manufacturer calibration by default; if an ISO17025 accredited calibration is desired for a new device, please contact Tech Sales.

    ISO17025 accredited calibrations are performed in-house in accordance with DIN EN ISO/IEC 17025:2018. Thorlabs GmbH's calibration laboratory is accredited by the German Accreditation Body (DAkkS), the national accreditation authority of the Federal Republic of Germany. The scope of services is described here in English or German. Accredited calibrated power and/or energy meter electronics come with a dedicated certificate of calibration proving the specified accuracy and traceability of calibration data. This certification may be required in certain applications or industries, such as the medical market.

    In contrast, our manufacturer calibrations are subject to the quality management requirements of ISO9001. The certificate of calibration lists the equipment used for the calibration procedure as well as the calibration data acquired. The manufacturer calibration of a power sensor includes recalibration of a single-channel console or interface at no additional cost. If you wish to calibrate one or more sensors with a dual-channel console, each sensor and console calibration service will need to be purchased individually.

    Both types of calibration can be offered for third-party equipment or adjusted for special requirements upon request. Please reach out to Tech Sales for further details.

    We recommend recalibrating your Thorlabs sensor and console as a pair; however, each may be recalibrated individually. To ensure accurate measurements, we recommend recalibrating annually. To order one or more sensor recalibrations with a dual-channel console, we offer two options: either 1) fill out the Returns Material Authorization (RMA) form with each console and sensor Item # to be recalibrated and specify either manufacturer calibration or ISO17025 accredited calibration in the "Further Details" field, or 2) separately add each recalibration service Item # offered below to your cart.

    Handheld Power Meter with iPad

    Figure 113A  The PM160 wireless power meter, shown here with an iPad mini (not included), can be remotely operated using Apple mobile devices.

    This tab outlines the full selection of Thorlabs' power and energy sensors. Refer to Table 113B for power meter console and interface compatibility information.

    In addition to the power and energy sensors listed below, Thorlabs also offers all-in-one, wireless, handheld power meters and compact USB power meter interfaces that contain either a photodiode or a thermal sensor, as well as power meter bundles that include a console, sensor head, and post mounting accessories.

    Thorlabs offers four types of sensors:

    • Photodiode Sensors: These sensors are designed for power measurements of monochromatic or near-monochromatic sources, as they have a wavelength dependent responsivity. These sensors deliver a current that depends on the input optical power and the wavelength. The current is fed into a transimpedance amplifier, which outputs a voltage proportional to the input current.
    • Thermal Sensors: Constructed from material with a relatively flat response function across a wide range of wavelengths, these thermopile sensors are suitable for power measurements of broadband sources such as LEDs and SLDs. Thermal sensors deliver a voltage proportional to the input optical power.
    • Thermal Position & Power Sensors: These sensors incorporate four thermopiles arranged as quadrants of a square. By comparing the voltage output from each quadrant, the unit calculates the beam's position.
    • Pyroelectric Energy Sensors: Our pyroelectric sensors produce an output voltage through the pyroelectric effect and are suitable for measuring pulsed sources, with a repetition rate limited by the time constant of the detector. These sensors will output a peak voltage proportional to the incident pulse energy.

    • As the PM100D and PM400 consoles and the PM100USB interface can only support repetition rates of up to 3 kHz, they should not be used with the ES408C sensor, which detects repetition rates up to 10 kHz.

    Power and Energy Sensor Selection Guide

    There are two options for comparing the specifications of our Power and Energy Sensors. Tables 113C, 113D, 113E, and 113F sort our sensors by type (e.g., photodiode, thermal, or pyroelectric) and provide key specifications.

    Alternatively, the selection guide Figures 113G and 113H arrange our entire selection of photodiode and thermal power sensors by wavelength (Figure 113G) or optical power range (Figure 113H). Each box contains the item # and specified range of the sensor. These graphs allow for easy identification of the sensor heads available for a specific wavelength or power range.

    Table 113C  Photodiode Power Sensors
    Table 113D  Thermal Power Sensors
    Table 113E  Thermal Position & Power Sensors
    Table 113F  Pyroelectric Energy Sensors
    • The response time of the photodiode sensor. The actual response time of a power meter using these sensors will be limited by the update rate of your power meter console.
    • The power range provided is for lasers with a repetition rate of 80 MHz. Because the peak power and peak power density are dependent on the average power and repetition rate of the laser, the upper limit to the working average power range will be lower for lower repetition rates. Please see the Specs tab here for more details. 
    • Typical natural response time (0 - 95%). Our power consoles can provide estimated measurements of optical power on an accelerated time scale (typically <1 s) when the natual response time is approximately 1 s or greater. As the natural response times of the S415C, S425C, and S425C-L are fast, these do not benefit from accelerated measurements and this function cannot be enabled. For more information, see the Operation tab here.
    • With intermittent use: maximum exposure time of 20 minutes for the S401C, otherwise maximum exposure time is 2 minutes.
    • All pyroelectric sensors have a thermal time constant, τ. This value indicates how long it takes the sensor to recover from a single pulse. To detect the correct energy levels, pulses must be shorter than 0.1τ and the repetition rate of your source must be well below 1/τ. Please see the Specs tab here for the τ value of each sensor.

    This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The analog output Bandwidth is DC-100 kHz dependent on the sensor. For the photodiodes sensors you can find the output bandwidth dependent on the current range in the manual on page 68 https://www.thorlabs.com/thorcat/17600/PM100D-Manual.pdf . I will contact you directly to check your application in more detail.

    A response from Julien at Thorlabs: Dear Martin, I am really sorry about this inconvenience. We will ship you a replacement immediately. Concerning your question about the quality control, we do check each power meter individually before shipment. I unfortunately do not know what the exact problem with your console is but I assume something must have happened during the shipment. We will inspect the unit as soon as we have it back and take the appropriate measures to prevent such issue from happening again. I will contact you directly to sort out the shipping details for the replacement.

    I have unpacked my PM204 (consists of a PM200 and a S120VC) but it is not reading anything. The measured value remains inf as well as the minimum and maximum value. Also in the applied software I don`t see any reading (value remains 0 or ---). I have auto ranging on an tried with several light conditions. In the software an indicator shows A (waiting for new measurement value)(in the left top corner) while I expect sometimes a T of "trigger". The detector itself is ok since it is functioning on a PM100D console. I have attached also a second detector (S155C)on the PM200 without success. I have checked for firmwareupdates but there are non available on the website. I can not find any reset functions or trigger-arm functions in the manual nor in the software. Did anybody check the console before chipping? That must be since a callibration sheet was shipped with it?!?! How do I fix it? Martin

    Each kit includes our PM100D or PM400 console, a S130C photodiode power sensor, and a post assembly, consisting of a BA2 base, PH2 post holder, and TR2 Ø1/2" post. The kit's slim sensor head is ideal for use in tight spaces as it is only 0.2"
    (5 mm) thick at its sensor. A sliding neutral density filter extends the power range that the sensor can be used to measure. With the filter out of the beam path, the power detection range is
    500 pW to 5 mW. With the filter in the beam path, power detection from 50 nW to 500 mW is possible; however, power levels below 5 mW should be detected without the filter in the beam path for optimal results. The filter's position is automatically detected and accounted for by the power meter console.

This is a general-purpose kit for customers working with higher powered lasers (up to 10 W) or longer wavelengths (up to 20 µm). The S425C thermal sensor has an exceptionally fast response time of 0.6 s.

    Thorlabs offers an in-house NIST traceable recalibration service for these power and energy meter kits, which can be ordered using Item # CAL-THPY below. Enter only the Part # and Serial # of the sensor that requires recalibration and include the corresponding console for recalibration during shipment.

    We recommend recalibrating your sensor and console as a pair; however, if you would like to recalibrate only your console, use Item #s CAL-PM1 or CAL-PM1D below.

    We also offer an ISO17025 accredited calibration for the PM100D and PM400 consoles separately. For more information or to order the accredited calibration, use Item # CAL-PM1D below.

    Thorlabs offers traceable recalibration services for our photodiode optical power sensors. To ensure accurate measurements, we recommend recalibrating the sensors annually. The manufacturer calibration of a power sensor includes recalibration of a single-channel console or interface at no additional cost; this is unavailable for the accredited calibration option. If you wish to calibrate one or more sensors with a dual-channel console, each sensor and console calibration service will need to be purchased individually. For more details on these recalibration services, please click the Documents () icons below.

    Refer to Table 236A for the appropriate calibration service Item # that corresponds to your power sensor.

    Requesting a Calibration
    Thorlabs provides two options for requesting a calibration:

    1. Complete the Returns Material Authorization (RMA) form. When completing the RMA form, please enter your name, contact information, the Part #, and the Serial # of each item being returned for calibration; in the Reason for Return field, select "I would like an item to be calibrated." In the Further Details field, please indicate "Manufacturer Calibration" or the desired calibration part number below in order to differentiate from the ISO17025 accredited calibration option. Once the form has been submitted, a member of our RMA team will reach out to provide an RMA Number, return instructions, and to verify billing and payment information.
    2. Select the appropriate sensor calibration Item # below, enter the Part # and Serial # of the sensor that requires recalibration, and then Add to Cart. If you would like a console calibrated with your sensor, repeat this process for Item # CAL-PM1 or CAL-PM2 below, entering the console Item # and Serial #. A member of our RMA team will reach out to coordinate the return of the item(s) for calibration. Note that each console calibration Item # represents the cost of calibrating a console alone; if requesting a single-channel console calibration with a sensor calibration, the appropriate discount will be applied when your request is processed. Should you have other items in your cart, note that the calibration request will be split off from your order for RMA processing.

    Please Note: To ensure your item being returned for calibration is routed appropriately once it arrives at our facility, please do not ship it prior to being provided an RMA Number and return instructions by a member of our team.
