消偏振分光棱镜(NPBS)

 

Description:

Non-Polarizing Cube Beamsplitter(NPBS Cube) consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S- and P-polarization states to be within 5% of each other. This means that they will not change the state of polarization of the incident beam.

 

Features:

  • Low polarization dependence;

  • Low power application;

  • Not change the state of polarization of the incident beam.
