Polarizing Beam Splitter Dichroic Glass Cube
Polarizing Beam Splitter Dichroic Glass Cube
FEATURE
1. Polarizing beam splitter prism can divide the incident non-polarized light into two beams of vertical linear polarization light
2. P-polarized light passes completely, while S-polarized light is reflected at 45 degrees, the emitting direction forms an angle of 90 degrees with P light
3. The polarized beam splitter prism is glued by two high-precision rectangular prisms, and one of the prisms is coasted with polarized beam split dielectric film on beveling
