Beam splitter
CO2 laser system for the beam splitter

 Beam splitter can press a certain percentage reflection, and allow the remaining incident energy of energy transmission in the past. In most cases, the beam splitter Angle, the wavelength and of polarization sensitive.

Most of the beam splitter coating is highly sensitive to polarization. Therefore, if the light polarization state is changing with time (such as in some random polarization laser), the beam splitter transmission rate will also change over time.

Here the beam splitter special referred to 10.6 apms vs. Length with 45 ° light of McCain's incident. When in this incident, s view of polarization and p polarization transmission rate/reflectance will have obvious difference. In your order these optical element, please be sure to specify the laser polarization state. (please refer to the "tutorial: polarization < >" http://www.iiviinfrared.com/cn/tutorials/polarization.html, in order to understand the s polarization and p polarization definition.)

Disc beam splitter
Ordinary beam splitter used to separate or combined with a laser beam. Polarization is used to separate or spectroscope would combine the two orthogonal polarization in the performance of the beam splitter lm. Mainly depends on the coating properties.
