Beamsplitter Cube, Non-polarising, 900-1200nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Non-Polarising beamsplitter cubes with a spectral range from 900nm to1200nm are constructed by cementing two precision right angle prisms together with metallic-dielectric coating on the hypotenuse surface. Absorption loss due to coating is around 10 %. Due to coating design, these cubes do not affect the polarization of the beam.
