About 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.
