The GMB1/M optic mount, which is designed to hold Ø25.4 mm optics up to 6.4 mm thick, features true gimbal motion in order to eliminate crosstalk when steering a beam of light. The point of rotation for both axes is located at the center of the mounted optic’s surface. Utilizing locking thumbscrews and fine pitch adjusters, the GMB1/M offers both coarse adjustment and fine tuning.The coarse adjustment allows 360° of manual positioning for both angular degrees of freedom. The fine adjustment allows for ±15° of control, with rotation of the control knob yielding 1° of angular displacement per revolution. The yaw can be adjusted in a similar fashion using the thumbscrew and setscrew closest to the post. After the desired pitch and yaw position is established, the entire mount can be easily locked into place by tightening both thumbscrews and both setscrews.

• Angular Displacement per Revolution: 1°
• Maximum Optic Thickness: 6.4 mm
