LBTEK-60 mm coaxial rotation adjustment mount

Product Description

Suitable for anisotropic optical components (such as polarization optics)
Choice of set screw fixation or retaining ring fixation
Mounts Ø50.8 mm optical components
360° rotation with 1° scale precision, angle numbers engraved every 10°
Compatible with 60 mm coaxial systems

LBTEK coaxial rotation mounts come in two models: CRM-2A and CRM-2B, suitable for mounting Ø50.8 mm optical components. The CRM-2A features internal SM2 threads and includes an SM2R retaining ring for securing optical components with a maximum thickness of 12.8 mm. The CRM-2B has a smooth inner wall and requires M4 nylon-tipped set screws to secure optical components with a minimum thickness of 7.9 mm. The mount allows for continuous 360° rotation with 1° scale markings, and angle numbers are engraved every 10°. The side is equipped with an M4 nylon-tipped locking screw (compatible with a 2 mm hex wrench) to lock the rotation. The bottom has an M4 threaded hole for connecting to a post.
