High Power Polarizing Beam Splitter Cubes
|
Materials: BK7, fused silica or SF5 optical glass.
Consists of a pair of right angle prisms optically bonded
with a dielectric
coating on the hypotenuse of one
prism.
No cement in the interface. Suitable for high power.
S-polarized light reflected at 90deg.,
P-polarized light transmitted with minimal deviation.
High
extinction ratio ( > 500:1
) over specified
range of wavelength.
Two versions available: Broadband and Narrowband
(for laser lines)
