Polarized beam splitter

The polarizing beam splitter prism is made of two high-precision right-angle prisms glued on the bevel, and coated with a polarizing beam splitter film on the bevel, which can divide the incident non-polarized light into two vertical beams of linearly polarized light. The P polarized light passes through completely, while the S polarized light is reflected at an angle of 45 degrees, and the outgoing direction is at an angle of 90 degrees with the P light. The polarizing prism with high extinction ratio produced by Hanzhong Borisun Optics is made of RoHs standard optical glass and coated with imported vacuum coating equipment, which can produce customized reflection/transmission films of various specifications.
