SL Gimbal Optical Mount, Ø8.0 in., 2 BD Differential Micrometers

The SL20ABD Gimbal Optical Mount facilitates fast, accurate positioning of large 8.0 inch (203.4 mm) circular or rectangular optics. Unlimited rotation in elevation and azimuth allow the mount and optic to be oriented in any position in space. Circular optics smaller than the mount’s nominal diameter are securely held inside the mount ring by extendible clamp arms. Circular and rectangular optics larger than the nominal diameter may also be attached to the mounting ring with external clamps. For added versatility, a large aperture in the base allows light to pass through unobstructed. A clutch nut on each axis allows the mirror to be quickly oriented in any coarse position. Locking the clutch nuts enables up to ±0.75° fine adjustment with differential micrometers.
