CO2 Laser Beam Splitters
CO2 Laser Beam Splitters
Partial reflectors are used in laser cavities or outside the laser to split the beam. Generally, windows are used at 45° AOI outside the laser cavity and concave lenses are used at normal incidence inside the laser cavity.
The polarization needs to be considered when specifying a beamsplitter otherwise the reflected and transmitted beams will not have the correct power. Our special polarization insensitive coating eliminates polarization considerations by reflecting 50% of both S and P polarization. Circularly polarized beams are split equally into two circularly polarized beams.
This 50% Polarization Insensitive Beam Splitter is Optimized for 10.6um @ 45° AOI
There is no transmittance in the visible.
In addition to offering coating services to our customers, we also sell ready to ship ZnSe Beam Splitters. Made in the USA. No minimum order.
