Polarizing Beam Splitter Cubes
(Cemented)
|
Materials: BK7, fused silica or SF5 optical glass.
Consists of a pair of right angle prisms optically
cemented with a dielectric
coating applied to the
hypotenuse of one prism.
S-polarized light reflected at 90deg.,
P-polarized light transmitted with minimal deviation.
Two versions available: Broadband and Narrowband
(for laser lines)
Suitable for low power, low energy applications.
( Compare: High power PBS )
