UV/VIS Dichroic Mirrors

UV/VIS dichroic mirrors have special multilayer dielectric coatings that enable reflectance of a primary UV laser wavelength with good broadband VIS/NIR transmittance. Dichroic mirrors are typically used for beam combining or beam separation. The standard dichroic mirrors listed below have UV laser-grade fused silica substrates and are optimized for use at 45°, with other angles available on request. Other UV-reflecting wavelengths from 145 nm to approximately 355 nm are also available.

 
UV/IR Dichroic Mirrors
UV/IR dichroic mirrors are designed to reflect a UV laser wavelength while transmitting wavelengths into the infrared. These coatings are specially modified multilayer dielectric designs, electron beam deposited onto high-quality CaF2 substrates. Our UV/IR dichroic mirrors reflect a UV wavelength specified below with usable transmittance out to approximately 8 µm.
