Standard 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.
Standard cube beamsplitters are usually used for energy splitting in situations where the polarization state is not sensitive.
Due to the split coating being all dielectric, there is no problem of light energy absorption.

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.
