Laser Line Polarization Beamsplitter Coatings(LPS)
This coating is designed to reflect nearly 100% of the S-Polarization and transmit 100% of the P-polarization within a narrow wavelength bandwidth. It's main application is to be used as polarizing beamsplitter in single wavelength laser system.

Dichroic Beamsplitter Coatings(DPS)
The main application of this coating is to act as a bandpsss filter. The DBS-SP coatings resulting high transmission for short wavelengths and high reflection for long wavelength, and the inverse case for DBS-LP coating. The DBS-HP coatings are used to separate harmonic generated lasers. The following graphics show the contrasted transmission for 1064nm laser and 532nm its second harmonic laser.
Short-wave pass dichroic beamsplitter(Part No.:DBS-SP)
