ZnSe Beam Splitter

The ZnSe beam splitter splits input light into two, one part is transmitted while the other is reflected. The transmission and reflection of the light depend upon various parameters such as the incident angle, state of polarization, and wavelength of the input beam. Our company is capable of making Zinc Selenide beamsplitters (i.e., for CO2 optics) at 9.4µm and 10.6µm wavelengths. There is a substantial difference in the transmittance and reflectance values of s and p polarization at a 45° incident angle, so the beamsplitters designed here are for this angle.
