Beamsplitter Coatings
Beamsplitter coatings split the incident energy, transmitting a portion and reflecting another portion. We offer both energy beamsplitting products and dichroic (spectrum) beamsplitting products from 400 to 2000 nm with two different devices, the cube beamsplitter and the flat plate beamsplitter.
The coatings consist of two types. Metallic beamsplitting coatings offer good performance over a moderate spectral region. When using metallic beamsplitters we do not recommend using high power lasers due to the absorption of the metallic film. Dielectric beamsplitting coatings can be designed for either narrow or broad wavelength ranges. They offer the advantages of minimal absorption and much higher resistance to abrasion.
