Beam-Splitters are used for laser beam splitting into two or more beams in various optical designs or for production of laser output couplers. We offer broad range of beam splitters optimized for customer apllications and in various configurations. Optical elements could be produced for single wavelegth or broadband from range of 250-2500 nm with desire splitting rates (R/T).

Partial reflection (PR) Beam-Splitters could be produced at various ratios - 30:70, 50:50, 70:30 and others. They can also be optimized for one wavelength or several wavelengths. Broadband PR Beam-Splitters can split beam in broader spectral region like 400-700 nm, 700-1200 nm etc. With non-zero angle of incident PR splitters also can be optimized for S, P or average polarization. However, simple PR coatings are highly sensitive to polarization of an incident beam. If equal splitting ratio for both polarization is desired, non-polarizing Beam-Splitters are available. They typically have 1.5-3% difference in splitting ratio for different polarizations.

Beam-Splitters with partial reflection could be provide as cubes or as plates, depending on your requirements of actual optical system and require specifications.
