Manual Rotary Translation Stage RP-1A

The manual rotary translation stage RP-1A from LBTEK achieves 360° continuous rotation. The rotating disk's circumferential scale has 1° graduation intervals with vernier markings achieving 5′ accuracy. A lateral thumb screw enables coarse/fine adjustment switching: loosening the thumb screw permits manual coarse rotation, while tightening the thumb screw locks coarse motion and engages micrometer fine adjustment. The micrometer screw has 10 main scale divisions corresponding to a ±5° rotation adjustment range and 50 vernier subdivisions corresponding to an accuracy of 60′/50 = 1.2′ (0.02°), and can be locked by its adjacent thumb screw. Simultaneously locking both the rotating disk's lateral thumb screw and the micrometer's adjacent thumb screw secures the entire rotating platform. The rotating disk features M6, M4, M3 tapped hole arrays for same-thread components, prism mount clamping arms, and 30mm coaxial system posts. Base countersunk tapped holes are used to install the rotary stage on M6-tapped optical tables or breadboards. The lateral M6 tapped hole accepts Ø 12.7 mm optical posts. The rotary stage center has an SM1 screw thread and comes with an SM1R retaining ring that can accommodate standard Ø 25.4mm optical components or SM1 lens tubes.
