The LFM-1A Lens Focusing Mount translates optical elements along their axis without side motions or rotation. To improve position resolution and focusing sensitivity, the internal mechanism incorporates an 80-tpi threaded barrel. By rotating the outer barrel, you will smoothly translate your optic up to 0.2 in. (5 mm), with precise accuracy. To secure your position, a series of locking screws are conveniently located around the adjustment barrel.

LFM-1A accommodates 1.38 in. (35 mm) diameter optics directly using the Delrin retaining rings supplied. A threaded LPLH-1T optic holder with a retaining ring for 1.0 in. (25 mm) optics is also supplied. If your application requires the positioning of a microscope objective, our LPMH-1 Objective Adaptor (0.800-36 thread) can be purchased separately. LFM-1A has tapped mounting holes for easy attachment to posts or other optical hardware.
