Single Wavelength Partial Reflective Coating
When a narrow wavelength radiation is incident on Single wavelength partial reflective coating, part of the radiation is reflected and the other part is transmitted. This coating always show a high reflectivity for S-polarization radiation and high transmission for P-polarization radiation. The main application of this coating is for a beamsplitter with 45 angle of incidence. It is the most commonly used, low-cost anti-reflection coating, and widely used in Lens & Prism, Input & output surface.

Broadband Wavelength Partial Reflective Coating
Broadband Wavelength Partial Reflective coating has similar performance to that of Single Wavelength Partial Reflective coating. However, Broadband Wavelength Partial Reflective coating can split the incident radiation over a wide spectrum, not Single Wavelength Partial Reflective. It can be widely used to split the incident radiation over a wide spectrum.
