The lens clamp uses the standard SM1 thread screw, can install Φ1 inch optical opponent. The maximal thickness of the optical component is 5.5mm. Gimbal mirror mounts are kinetic flexible to eliminate the disturbance when light beam turns.
360°manual course adjustment can be achieved when the alary screw and the fastening screw furthest from the rod are loosed. After tightening the alary screw, ±15°tilt adjustment can be achieved. When the fine tuning knob rotates one circle, the rotation angle of lens clamp is 0.865°. The maximal angle error in contiguous two circles is 31", the average error is 10".
The rotating point is at the center of the optical component.
