Manual Rotary Translation Stage RP-1A-KIT

The manual rotary translation stage kit RP-1A-KIT from LBTEK, assembled from rotary stage RP-1A and adapter plate RP-1A-AP, delivers 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 it 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. Components RP-1A and RP-1A-AP are available separately.
