Partial Reflective Coating
Partial reflective coating is always used in
beamsplitters application. There are some kinds of partial
reflective coating.
Single Wavelength Partial Reflective
Coatings (SPR)
When a narrow wavelength radiation is incident on
SPR 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 degree 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 Coatings (BPR)
BPR coating has
similar performance to that of SPR coatings. However, BPR coating
can split the incident radiation over a wide spectrum, not SPR. It
can be widely used to split the incident radiation over a wide
spectrum.
