Low wavefront distortion gimbal mirror mounts are designed to hold mirrors in a way that will not induce optical distortion. They use an axial three-point mounting method to gently, but securely, hold optics with tight flatness tolerances.
- Designed to minimize wavefront distortion
- True gimbal adjustment
- 45 degree aperture chamfer for beamsplitting applications
- Configurable for right- and left-handed operations
- Steel construction for maximized stability See All Features

Features
Highly Stable Gimbal Mounts
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.
Ideal for Beam Splitting Applications
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.
Different Actuator Types
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.
