SL Series optical mounts are true gimbal mounts for high-resolution azimuth and elevation adjustment of mirrors and beam splitters, greatly reducing beam wander and optical path-length changes. The fixed rotational axes intersect at the front surface of the optic, allowing simple, non-coupled rotation without translation. These mounts feature all steel construction for superior stiffness and stability.

The SL series mounts can fit various diameter and type of optics. The fixed rotational axes intersect at the front surface of the optic, allowing simple, non-coupled rotation without translation. The gimbal design also greatly reduces beam wander and optical path-length changes. These mounts are designed for maximum clear aperture of the transmitted beam at a 45° incident angle in beamsplitting applications.

SL Mounts are designed with two different types of actuators for convenience. For general applications, BM Micrometer drives supply graduated settings for repeatable positioning and BD Differential Micrometers are specifically suited for ten times higher positioning sensitivity.
