The ultraviolet beamsplitter divides an incident beam into reflected and transmitted beams in a specified ratio. Its operating band is concentrated in the ultraviolet region, typically about 200-400 nm. It is usually made from UV grade fused silica, with a partially reflecting coating on one surface and an antireflection coating on the other. Ultraviolet light incident at 45° is split close to the customized ratio, with very low absorption loss and a smooth spectral response.

Dichroic mirrors separate beams by wavelength. A shortpass dichroic mirror transmits wavelengths below its cutoff and reflects wavelengths above it, providing high transmission and reflection. Different cutoff wavelengths are available. Average transmittance and reflectance can both exceed 90% within the specified bands. One surface has a filtering coating and the other an antireflection coating; the arrow points toward the filtering surface.
