High Quality Polarizing Beamsplitter Prism (PBS)
Polarization Beamsplitter Prism (PBS) is generally made of two right-angle prisms with hypotenuse glued or optical glue, and a polarization beamsplitter film is coated on the slope, so that the P-polarized light in the incident light is transmitted, while the S-polarized light is reflected.
All beam incident and exit surfaces are generally coated with anti-reflection coatings.
