Technical Description
The 30 mm rotation mount provides 360° continuous rotation and smooth adjustment for precise positioning of waveplates, polarizers, and other polarization optics. It holds Ø1-inch optics up to 9.4 mm thick, secured by the included CSK3 retaining ring. Thicker optics can be used with an SM1-series lens sleeve threaded into the mount.
The CRD-25 features a 2°-division rotation mechanism, allowing manual positioning and locking with a side setscrew. For higher precision, choose the S/N0007 model with a micrometer head. When locked, the precision micrometer enables fine adjustment within ±7°, with a vernier resolution of 5 arcminutes.
To integrate the rotation mount into a cage system, two LPCM-series cage plate adapters can build a 60 mm cage frame on both sides. The MPV-LK3 prism mount (12.7×42.7 mm platform) attached in front serves as an accessory, enabling free rotation without cage rod interference while preserving the 30 mm cage system optical axis.
The mount can be attached to a Ø12 mm stainless steel post via the bottom M4 threaded hole for free-space experiments.
