Optical Surfaces offers custom beam splitters which play a key role in dividing, recombining, and managing the directions of multiple beam paths in optical systems.
Using beam splitters, light may be divided into separate wavelengths and/or polarization states. In addition, they can split light to provide specific values of transmittance and reflectance.
The custom beam splitters offer higher flatness and parallel specifications than is routinely available. Typically, OSL beam splitters are manufactured to a surface accuracy of lambda/20 p-v at 633nm, a surface quality of 10/5 and microroughness of less than 1.2nm rms. Beam splitters can be supplied with an extensive range of coatings designed to operate at your required angle of incidence.
