LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Suitable for anisotropic optical components (such as polarizing optical elements)
Optional set screw fixation or retaining ring fixation
Mounted with Ø50.8 mm optical components
Comes with 360° rotation and 1° scale precision, angle numbers marked every 10°
Compatible with 60 mm coaxial systems

The LBTEK coaxial system rotary mounts come in two models, CRM-2A and CRM-2B, suitable for mounting Ø50.8 mm optical components. The CRM-2A features SM2 internal 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 the use of M4 rubber-tipped set screws to fix optical components with a minimum thickness of 7.9 mm. The mount allows continuous 360° rotation with 1° scale precision, featuring angle markings every 10°. It includes an M4 rubber-tipped locking screw on the side (compatible with a 2 mm hex wrench) to secure the rotation position, and an M4 threaded hole at the bottom for connecting to mounting rods.
