A beam splitter is typically a glass plate or cube that has been coated with dielectric or metal film to reflect a portion of the incoming light while allowing the rest to pass through. In most cases, the structure and the coating film in the beam splitter determine the beam splitter’s properties and functionality.
There are different types of beam splitter: the dichroic filter separates different wavelengths from a broadband beam; non-polarizing beam splitter will split the beam into two beams with similar polarization but with different or equal power, where the power ratio depends on the coating design; and polarizing beam splitter will split beams into S and P beams respectively.

The common glass beam splitter is used to split the laser beam. The performance of beam splitters is mainly dependent on the coating specifications. Material: Fused Silica, N-BK7 |
With non-polarizing beam splitter coating on hypotenuse face, this series of cube beam splitters provide 50:50 split ratio independently on the input beam polarization. Material: N-BK7 | 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. There is a substantial difference in the transmittance and reflectance values of s and p polarization at a 45° incident angle, so the ZnSe beam splitters designed are for this angle. Diameter Tolerance: +0/-0.13mm |
