2-CPW-TFO-L/4-0940 - Crystalline quartz λ/4 Waveplate, >18 mm Clear Aperture, mm, 940 nm

Waveplates are coated with dielectric AR layers for the mid-IR range in order to reduce Fresnel losses. Characteristic plates thickness is 0,2 - 1,0 mm. Generally, the waveplates are mounted into the metal holder for easier handling and adjustment.
