Beamsplitter coatings 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), non-polarizing (polarization insensitive) or dichroic (spectral separation).

 

Please contact us with your requirements and we will provide you a solution with coating design optimized for you application.

Partial reflection (PR) coatings are used for beam splitting at various ratios - 30:70, 50:50, 70:30 and others. They can also be optimized for one wavelength or several wavelengths. Broadband PR coatings can split beam in broader spectral region like 400-700 nm, 700-1200 nm etc. Non-normal incident PR coatings 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 PR coatings are available. They typically have 1.5-3% difference in splitting ratio for different polarizations.

Cube beamsplitters split incident beam into two output beams separated by a 90 degree angle at narrow wavelength region.   Polarizing cube beamsplitters separate the s- and p-polarized components of an incident beam while non‑polarizing cube beamsplitters provide analogical way of splitting, but are not sensitive to incident polarization.   Typical spectral curve of non-polarizing cube, designed for 830 nm wavelength is shown.
