Adjustable Lens Mounts

• LH1 Mounts Optics from Ø0.28" (Ø7.1 mm) to Ø1.80" (Ø45.7 mm)
• LH2 Mounts Optics from Ø0.77" (Ø19.6 mm) to Ø2.28" (Ø57.9 mm)
• 8-32 (M4) Tapped Hole for Mounting to Ø1/2" Posts

These adjustable lens mounts are ideal for general-purpose mounting of non-standard optic sizes. The non-marring Delrin^® fingers can be individually adjusted for unusual shapes in addition to being reversible, providing a flat side and a V-shaped side. The aluminum mount and Delrin^® fingers have laser-engraved witness lines and millimeter scales, respectively. The scales on the fingers offer minor ticks every 1 mm and major ticks spaced 5 mm apart. These ticks along with the engraved lines allow for more repeatable positioning and help with optic centration within the mount.

A bottom-located 8-32 (M4) tapped hole allows for direct fastening to our Ø1/2" Posts.

Thorlabs' LH160C(/M) Adjustable Lens Mount is compatible with our 60 mm Cage Systems and is ideal for general-purpose mounting of non-standard optic sizes. The non-marring Delrin^®* fingers can be individually adjusted for unusual shapes in addition to being reversible, providing a flat side and a V-shaped side. The optic or object may be manually aligned and then locked into place by tightening the three black thumbscrews in the Delrin fingers. The aluminum mount and Delrin fingers have laser-engraved witness lines and millimeter scales, respectively. The scales on the fingers offer minor ticks every 1 mm and major ticks spaced 5 mm apart. These ticks along with the engraved lines allow for more repeatable positioning and help with optic centration within the mount.

The mount features four through holes compatible with our Ø6.0 mm cage rods and 60 mm cage system. Two 0.05" (1.3 mm) hex setscrews for each rod lock the mount into place. The mount also features SM2 (2.035"-40) threading for compatibility with our SM2 Lens Tubes and a bottom-located 8-32 (M4) tapped hole that allows for direct mounting to our Ø1/2" Posts. Please note that the three Delrin fingers prohibit mounting SM2-threaded components on the front of the LH160C(/M) mount.
