Beam-Splitter (BS) is a term used to describe various coatings which divide a beam of light into separate beams. Dichroic filters, covered in our Color Filter section, are often called beam-splitters. However, in this section, we will be speaking specifically about beam-splitters that divide light at each wavelength of interest into the two separate beams with an incident angle around 45 degrees from normal.

Dielectric coatings, however, have the advantage of being non-absorbing and so allow for greater throughput of energy. For example, a dielectric coating can be used for a 50/50 beam-splitter coating. Inconel, on the other hand, can yield approximately 30% transmission and 30% reflection due to the absorption inherent in the metal film. Standard dielectric beam-splitter coatings include 30/70, 50/50, and 70/30. However, we would welcome any custom requirements you may have. Please feel free to contact us with your specifications
