HP Polarizing Cube Beamsplitters

Compared with the plate beamsplitters, the optical path length of the reflection and transmission light of the cube beamsplitters are equal, and there is no trouble with beam translation, ghost images, and interference.

Due to the split coating being all dielectric, there is no problem of light energy absorption.


Polarizing Cube Beamsplitters are usually used in applications where S-polarized light and P-polarized light in incident light need to be separated, and they can also be used as polarization components.

The P-polarized light of the incident light is completely transmitted, and the S-polarized light of the incident light is reflected in a vertical direction of 90°.

The level of separation of S light and P light is defined by the extinction ratio TP/TS.

Kindly Reminder

It should be noted that because this kind of split coating itself has an element of polarization effect, the transmitted beam is partially polarized.

If you want to avoid the influence of polarization sensitivity, it is recommended to use our XXX- polarization splitting prism, or XXX- depolarization splitting prism.
