Description

Details

Cubes are constructed by cementing two precision right angle prisms together with metallic-dielectric coating on the hypotenuse surface. Absorption loss to the coating is ~10%, but due to the metallic material of the coating cubes do not change polarization of the incident beam!

Features

All faces are Antireflection coated
Low polarization dependence
