Thorlabs' Mounted Bandpass Colored Glass Filters are manufactured from different colors of Schott® glass and are intended for use in a wide variety of applications. The SM1-mounted (1.035"-40), Ø25 mm filters will thread into our manual or motorized filter wheels or any of our lens tube accessories. The housing is engraved with the Item # and intended wavelength range for easy identification. If the bandpass filter you require is not listed here, it may be available in an unmounted version.

Several of the colored glasses used for our filters are fluorescent at certain wavelengths; please consider our fluorescence imaging filters if your application is sensitive to fluorescent signals. For narrowband sources, we recommend our dielectric bandpass filters.

Colored Glass Filter Kit
Thorlabs offers a boxed filter kit containing a selection of our most popular bandpass and longpass filters. For the specific filters included in the kit, please see the presentation at the bottom of this webpage.

Storage Box
If you need a safe, convenient place to store loose filters, consider our KT01 Storage Box, a lockable foam case that holds up to ten filters. Please see below for more information.
