High-Precision Rotation Stage DMRP-1T

JCOPTIX high-precision rotation stages accurately orient optics/optomechanics. They provide continuous 360° coarse rotation and ±5° fine adjustment, selected by a side thumbscrew. Unlocked, the top turns manually through 360°; 1° laser graduations and 5-arcmin vernier marks aid alignment/readout. Tightening locks coarse rotation and enables backlash-free ±5° micrometer adjustment. Each 1 micrometer turn rotates the stage 1°; 1 turn has 50 divisions, each corresponding to 0.02°. Platform diameter is Ø63.0 mm, axial horizontal load 12 kg, and radial vertical load 2 kg. M6, M4, 4-40 holes mount adjustable arms and 30 mm cage components. Base M6 countersunk holes mount horizontally to tables/breadboards; side M6 holes connect posts for vertical installation. Four models are described: DMRP-1TA stage/adapter assembly, DMRP-1T and DMRP-1TS separate stages, and DMRP-1T-AP adapter plate. The plate suits applications not needing a central SM1 hole. DMRP-1T-AP attaches to DMRP-1T or DMRP-1TS with four supplied 4-40 cap screws. High-precision rotation stages with micrometers. Models: DMRP-1TA, DMRP-1T, DMRP-1T-AP. Continuous 360° coarse rotation; ±5° fine adjustment at 0.02°/division; axial load 12 kg, radial load 2 kg. JCOPTIX stages provide precise optical orientation, continuous 360° coarse rotation at 1° accuracy, and ±5° fine adjustment at 0.02°. Three listed options are DMRP-1TA assembly, DMRP-1T stage, and DMRP-1T-AP plate, all Ø63.0 mm. Without its plate, DMRP-1T has a central SM1 aperture for Ø25.4 mm optics up to 17 mm thick. Four base M6 countersunk holes mount horizontally, or side M6 holes attach posts for vertical mounting. Thin high-precision rotation stage for free-space use. Model: DMRP-1TS. Continuous 360° rotation with vernier readout; ±5° micrometer adjustment; side M4 post holes; Ø25.4 mm optics up to 12.7 mm thick; SM1 tube/30 mm cage compatibility; 1 SM1RR ring included. JCOPTIX thin stages precisely orient optics, with continuous 360° coarse and ±5° fine rotation selected by a side thumbscrew. Unlocked, the top rotates manually through 360°, with 1° marks and 5-arcmin minimum vernier reading. Tightening locks coarse rotation and permits backlash-free ±5° fine adjustment. Each 1 micrometer turn rotates the stage 1°; 1 turn has 50 divisions, each 0.02°. At only 20 mm thick, the compact stage particularly suits post-supported free-space optics. Two bottom M6 countersinks also allow horizontal table mounting: 1. Choose position and start two M6 screws in the corresponding holes. 2. Adjust screw depth, then slide the stage horizontally so both M6 screws enter its two bottom M6 countersinks. 3. Rotate the top until its notch aligns with the M6 screw sockets and tighten at an angle with a ball-end key. 30 mm cage rotation adapter. Model: DMRP-1T30. Adapts 30 mm cages for continuous 360° rotation; installs 30 mm systems without rod removal; single-sided screw clamping. This JCOPTIX 30 mm cage adapter connects 30 mm components to DMRP-1T stages for precise micrometer adjustment. One side screw simultaneously clamps 2 rods of a 30 mm cage. Place the preassembled cage into the opened clamp, press down, and tighten the side screw without dismantling rods.
