NPCB13, Non-polarizing Cube Beamsplitters, 50R/50T, NIR Coating 700-1100nm, K9 Optical Glass


Non-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.

The beam splitting coating of the Non-polarizing Cube Beamsplitters usually adopts the mixed metal and dielectric coating, so the transmitted light retains the same polarization state as the incident light.

Kindly Reminder

Non-polarizing Cube Beamsplitters have low polarization, but this kind of special beam splitting coating has partial absorption of light power (the average absorption within the nominal bandwidth <10%).

It is recommended not to be used in the environment of strong laser power.
