Features
- SM05-Threaded (0.535"-40) Fixed Mounts
- Integrate SM05-Threaded Components such as Lens Tubes, Irises and Adapters
- Wide Range of Mounts Available
These SM05-threaded (0.535"-40) mounts allow a variety of optical components to be integrated into optomechanical setups. Thorlabs offers internally and externally threaded, 90° flip, and flexure stage mounts for Ø1/2" optics. Each of these mounts are designed to be mounted on Ø1/2" posts via an 8-32 (M4) tapped hole, except for the HCS020 Flexure Stage Mount, which allows SM05-threaded components to be mounted on a flexure system. All of these fixed mounts allow for versatility and flexibility in optomechanical constructions due to compatibility with SM05-threaded lens tubes, irises and adapters.

Zoom- Internal SM05 (0.535"-40) Threads
- Mounts Optics up to 0.20" (5.1 mm) Thick
- Optic Held in Place by SM1RR Retaining Ring (Included) and Back Lip
- 8-32 (M4) Tapped Hole for Mounting to a Ø1/2" Post
- Available Individually and in 5 Packs
The LMR05(/M) Fixed Optic Mount is a convenient way to mount Ø1/2" optics on TR Series posts using the 8-32 (M4) tapped hole on the base of the mount. Each LMR05 mount is internally SM05-threaded and has a back-edge lip on which the optic rests. The SM05RR Retaining Ring included with each mount can be used to secure the optic in place by sandwiching the optic between itself and the back lip. As an alternative to the included SM05RR retaining ring, SM05LTRR retaining rings for stress-free mounting of optics can be purchased separately.
The LMR05 is available individually and in 5 packs for ordering convenience. Each mount in the LMR05(/M)-P5 5 pack includes its own SM05RR retaining ring.
Zoom- Internal and External SM05 (0.535"-40) Threads
- Mounts Optics up to 0.21" (5.3 mm) Thick
- Optic Held in Place by SM1RR Retaining Ring (Included)
- 8-32 (M4) Tapped Hole for Mounting to Ø1/2" Posts
- Externally Threaded to Integrate Lens Tubes, Irises or Other Internally SM05-Threaded Components
The LMR05S(/M) Fixed Lens Mounts are internally SM05-threaded on one side and externally SM05-threaded on the other. The optic is secured in the mount with the included retaining ring and has an 8-32 (M4) tapped hole for mounting to a Ø1/2" Post. This mount functions as a lens tube that can be directly attached to a TR Series Post. The internal threading can hold unmounted optics up to 0.21" (5.3 mm) thick, while the external threading is just deep enough to allow for the mounting of lens tubes, irises, or other internally SM05-threaded components.
While the functionality of this part can be duplicated by combining a lens tube slip ring and a lens tube, this fixed mount offers a smaller package size.
Zoom- Internal SM05 (0.535"-40) Threads
- Mounts Optics up to 0.16" (4.1 mm) Thick Using SM05RR Retaining Rings (Sold Separately)
- 8-32 (M4) Tapped Hole for Mounting to Ø1/2" Posts
- Mount Externally SM05-Threaded Components on Either Side
The SMR05(/M) Lens Tube Post Mount features internal SM05 threading that extends the full length of the mount without any retaining lip. It is perfect for mounting lens tubes and other mounted optics, and can also be used to hold unmounted optics when used with two retaining rings (sold separately).
Please note that the SMR05(/M) does not include retaining rings, and two SM05RR retaining rings will be needed to hold unmounted Ø1/2" optics with this mount.
Zoom- Holds Ø1/2" Filters up to 0.38" (9.7 mm) Thick
- Post and Rod Mounted for Greater Flexibility
- Detent Force at 0º and 90º; Lockable Across Entire Range
- Includes 0.050" Hex Key and SM05RR Retaining Ring
The TR05F90 Flip Filter Mount can be post mounted as an individual unit or ER-cage-rod-mounted for stacking filters in a series. Since the depth of the filter mount is 0.5" (13 mm), the minimum length of the ER rod needed when creating a stack of filters is the number of filter mounts being stacked times 0.5" (13 mm). A precision detent mechanism provides holding force at the 0° and 90° positions, while a nylon-tipped setscrew allows the mount to be locked.
Please note that the threaded hole used to attach the post to the filter mount goes all the way through to the rotation mechanism. Be sure that no more than 0.2" (5 mm) of the screw on top of the post is threaded into the filter mount in order to prevent the binding of the rotation mechanism.

- Internally SM05 (0.535"-40) Threaded
- Mounts to Flexure Stage Systems
This mount is internally SM05-threaded to integrate our line of SM05-threaded accessories with any Thorlabs flexure stage systems. This mount is ideal for use with SM05 lens tubes to minimize stray light; other applications include use with the SM05PM5 linear polarizer holder in order to align PM fiber to a connector keyway. The optical axis of the mount is 0.49" (12.5 mm) above the flexure stage.
