Details

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.

ZO waveplates for mid-IR applications (2.800-9.000 microns)
