Dispersion prism
Dispersion prism
illustrate:
The polarization splitting prism is made of a pair of high-precision right angle prisms. The inclined edge of one prism is coated with polarization splitting dielectric film, which can divide the incident non polarized light into two vertical linearly polarized light. The p-polarized light passes completely, while the s-polarized light is reflected at an angle of 45 degrees, and the exit direction is at an angle of 90 degrees with the p-light. The high extinction ratio polarization splitting prism produced by Xinzhao is made of ROHS standard optical glass and coated with imported vacuum coating equipment, which can produce customized reflection / transmission films of various specifications.
