638 nm wave rotator plate 90° with brass mount

This is a pair of high-quality wave rotator plate dedicated for 620-660 nm wavelength and the brass mount. Using this optic it is possible to rotate the polarization axis of a linearly polarized light beam by an angle of 90 degrees.

High efficiency >99,8% for ~638 nm wavelength was obtained thanks to AR coating.

Dimensions of the rotator are 10 x 10 mm with ~5 mm thickness.

The mounting 2 x M3 threads are located at the bottom of the mount. The distance between holes is 8 mm.

You can also find rotators for 455 nm and 525 nm.
