Beam Splitters coating

Beam splitter coating can generate special high reflectance to S-polarztion and high anti-reflection to P-polarization for laser
application.It can achieve nearly 100% reflectance to S-polarization and 100% transmission for P-polarization on a narrow wavelength range. Therefore, its main application is to be used as polarizing beamsplitter for single wavelength laser system when it is deposited on glass substrate, but its extinction ratio is not so high.
