The optimal beamsplitter can take on many forms including cubes, plates, hexagons, pentagons, polarising, non-polarising or wedge designs in a wide variety of reflection / transmission ratios and substrates depending upon your application.

Optical Surfaces technical experts can advise customers on the key beamsplitter parameters to consider including wavelength range, physical size, polarisation and if used in an interferometer - pathlength and phase matching requirements.

Benefiting from a stable production environment and a skilled workforce - Optical Surfaces is able to produce custom beamsplitters that offer outstanding flatness and parallel specifications.

Typically Optical Surfaces 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 enhanced with an range of coatings designed to operate at your required angle of incidence.
