We look forward to hearing from you!
Thorlabs' Fixed Mirror Mounts were designed to meet the needs of OEM customers. To that end, we are equipped to manufacture these base plates in high volumes and with timed delivery. Additionally, we can design and manufacture modified versions of these base plates to meet your specific needs.
If you have a custom or OEM project, we invite you to contact us to discuss how our engineering expertise and manufacturing capabilities can help you achieve your goals.
Features
- Attach OEM Fixed Optical Mounts via 1/4"-20 (M6 x 1.0) Mounting Features
- Mount on Breadboard or Optical Table via 1/4" (M6) Clearance Hole
- Suitable for Vacuum Applications
Thorlabs' Base Plates for OEM Applications are designed to support a seamless transition from benchtop R&D to high-volume OEM laser system production. These base plates provide breadboard compatibility for prototyping flexibility and integration into full optical systems during the development phase. The mechanical footprint allows for direct transfer into the proven system, with a cavity-ready form factor supporting direct mounting into custom laser system substructures. This overall architecture enables OEM designers to rapidly develop and iterate optical systems on standard breadboards, then deploy those exact assemblies in production environments with no change in alignment geometry, reducing validation requirements and increasing long-term system reliability.
Each base plate is fabricated from unanodized 6061-T6 aluminum and double vacuum-bagged, making them suitable for cleanroom and vacuum chamber environments; vacuum specifications are provided in Table 1.1. Options include manual translation base plates, which provide up to 1.5" (31.8 mm) of linear mount travel, and rotation base plates, which offer up to 90° of rotational adjustment.

- Attach OEM Fixed Optical Mounts via 1/4"-20 (M6 x 1.0) Square Nut
- Mount on Breadboard or Optical Table via Clearance Hole for 1/4" (M6) Cap Screws
- Translation Slot Provides Up to 1.25" (31.8 mm) Linear Translation
These base plates provide compatibility between OEM fixed optic mounts and standard breadboards or optical tables. Each base plate includes four counterbored mounting holes for 1/4" (M6) cap screws to secure it to the optical table. Optic mounts are attached using two 1/4"-20 (M6 x 1.0) square nuts inserted into the translation clearance slots on the base plate. This configuration allows the mounts to be translated by up to 1.25" (31.8 mm) while the base plate remains stationary, as shown in Figure 803A.
The FMB2(/M) translation base plate is compatible with OEM fixed optic mounts designed for Ø1/2" (Ø12.7 mm) and Ø1" (Ø25.4 mm) optics. The FMB3(/M) translation base plate is compatible with mounts designed for Ø1.5" (Ø38.1 mm) and Ø2" (Ø50.8 mm) optics.

Figure 788A Two Rear-Loading Mirror Mounts with Dichroic Mirrors Mounted on FMB1 Base Plates
- Attach OEM Fixed Optic Mounts via 1/4"-20 (M6 x 1.0) Tapped Holes
- Included Dowel Pin Adapter Provides Pivot Point for Rotation
- Mount on Breadboard or Optical Table via Clearance Slot for 1/4" (M6) Cap Screws
- Clearance Slot Provides Up to 90° Rotation
The FMB1(/M) Rotation Base Plate provides compatibility between the OEM fixed optic mounts and standard breadboards or optical tables. Four 1/4"-20 (M6 x 1.0) tapped holes through the base plate match the footprint of all sizes of the OEM fixed optic mounts. An included dowel pin adapter is threaded into the central 1/4"-20 (M6 x 1.0) tap, providing a pivot point about which the base plate can rotate when placed in one of the holes of a breadboard or optical table. A curved clearance slot allows the base plate to be secured to a breadboard or optical table and provides up to 90° of rotation without removing the mounting cap screw.
