CRD-05 1/2-Inch Rotation Mount

Product Description

• Accommodates Ø1/2-inch optical components with a maximum thickness of 6.5 mm
• Features SM05 (0.535″-40) internal threaded hole, compatible with SM05 lens sleeves
• With SM1 (1.035″-40) external thread for mounting SM1 lens sleeves or connecting to 30 mm cage systems
• When used with a polarizing beam splitter cube, it enables continuous adjustment of transmitted polarized light, converting incident unpolarized or P-polarized light into circular, elliptical or linearly polarized light
• Includes one CSK05 retaining ring

The CRD-05 rotation mount is designed for mounting Ø1/2-inch optical components. The dial on the front of the mount enables 360° rotation with 2° graduation and is marked with a calibration line. A side set screw is used to lock the rotational position.

Technical Description

(1) The CRD-05 rotation mount is used for mounting Ø1/2-inch optical components. The front dial of the mount can rotate 360° with a graduation of 2° and is provided with a calibration line. The rotational position can be locked by tightening the side set screw with a 0.9 mm hex wrench.

(2) The SM1 (1.035″-40) external thread allows the mount to be directly screwed into SM1 internal thread components, such as SM1 lens sleeves or 30 mm cage cubes. The central aperture is machined with SM05 (0.535″-40) thread, which can hold Ø1/2-inch (Ø12.7 mm) optical components with a maximum thickness of 6.5 mm. Optical components are mounted with the included retaining ring.

(3) When used in combination with a polarizing beam splitter cube and the CRD-05 Ø1/2-inch rotation mount, the cube is ideal for constructing adjustable beam splitters, adjustable attenuators or beam combiners. A variable beam splitter can continuously alter the transmission intensity of linearly polarized light beams. The half-wave plate in the rotation mount first rotates the incident linearly polarized light, which then passes through the polarizing beam splitter cube and is split into S and P polarized light, thereby achieving continuous adjustment of the beam splitting ratio. This effect is commonly used in holography and interferometry.
