Waveplates, High Power, Zero order

Manufacturer's part number :


Manufacturer Altechna


Description :

Zero Order half waveplates and quarter waveplates with clear aperture of 18mm for specific wavelengths from 780nm up to 1500nm. 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. The waveplates are mounted into the metal holder for easier handling and adjustment.
