Manual Angular Translation Stage GPR2-25.4

The manual angular translation stage from LBTEK provides unobstructed pure rotary movement within a specified angular range through its precision arc-shaped T-slot design, which incorporates ball-spring mechanisms to eliminate machining gaps and enhance motion stability. Its compact, stackable design allows one stage to be mounted onto another's top plate to create dual-axis systems with coincident rotation points (GPR-25.4 mounted on GPR-44.4 achieves overlapping rotation centers for XY angular adjustment). The pre-assembled GPR2-25.4 offers direct dual-axis functionality. The micrometer head enables coarse repeatable positioning with a custom pitch (1° rotation per full turn, 2.4′ per division), complemented by differential scales on the side offering 10′ precision. A set screw (operated with the included 1.5 mm hex key) secures the stage at desired positions. The base features two M6 countersunk slots for mounting to breadboards, optical tables, or other stages, while the top plate includes M4 and M3 tapped holes for attaching posts, mirror mounts, or other components with M4 tapped holes/countersunks holes.
