Thorlabs LMR05 Fixed Lens Mount – LOT OF 2

The LMR05 is a fixed-lens mount for Ø ½-inch (≈ 12.7 mm) optics.

It includes a retaining ring (SM05RR) to hold the optic securely in place.

The mount is made from aluminum, which gives a good balance of lightness and structural stability

Accepts optics up to Ø = 0.5″ (12.7 mm)

Maximum optic thickness: 5.0 mm (0.21″)

Clear aperture: ≈ 11.0 mm (so note there will be a small edge-margin)

Optical height above mounting base: 16.0 mm

Mounting base has a standard 8-32 (or M4 in metric version) tapped hole — so you can mount it on standard ½-inch (or metric equivalent) posts or posts from the same ecosystem.
