Product Description
A Polarizing Beam Splitter (PBS) is typically formed by cementing or optical contacting the hypotenuse faces of two right-angle prisms. A polarizing beam-splitting coating is deposited on the inclined surface: P-polarized light in the incident beam is transmitted, while S-polarized light is reflected. Anti-reflection coatings are generally applied to all beam entrance and exit surfaces.
