Polarizing Beamsplitter Cubes
Optimised for popular laser wavelengths
 
Dual wavelength Polarizing cubes are also available
 
All Cubes are AR coated
 
Standard Polarizing cubes are available from stock
 
High Extinction ration (> 3000:1) cubes available upon request

Polarizing cubes for specified wavelength (250-2200 nm) AR coated on four input and output working surfaces. Polarizing Beamsplitter Cube split randomly polarized beams into two orthogonal, linearly polarized components: S polarized light is reflected at a 90° angle while P-polarized light is transmitted.

Polarizing Cubes for Medium Power Applications Each beamsplitter consists of a pair of high precision tolerance right angle prisms cemented together with a dielectric coating on hypotenuse of one of the prisms. Typical damage threshold of these cubes is >0.3 J/cm2 @ 1064 nm 10 ns at 20 Hz.

Polarizing Cubes for High Power Applications Optically contacted polarizing beamsplitter cubes used for high power applications can withstand energy fluencies up to 10 J/cm2 @ 1064 nm 10 ns at 20 Hz.
