High precision beamsplitters feature a range of coatings

Beamsplitters play a key role in dividing, recombining and managing the directions of multiple beam paths, in optical systems. Using beamsplitters - light may be divided into separate wavelengths and/or polarisation states. In addition, beamsplitters can split light to provide specific values of transmittance and reflectance. 

Optical Surfaces manufactures custom beamsplitters that offer higher flatness and parallel specifications. Typically OSL beamsplitters 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. Supplied mounted or unmounted, custom beamsplitters from Optical Surfaces can be supplied with an extensive range of coatings designed to operate at the required angle of incidence.

Optical Surfaces has experience and expertise in producing a wide variety of custom beamsplitters; this includes plate, wedge, cube, periscope, penta prism and custom shaped beamsplitters. In addition, Optical Surfaces has also produced dichroic, multi-wavelength, polarising and laser insertion beamsplitter prisms.
