Cube beamsplitter Prism

Cube beamsplitter


MaterialBK7、Synthetic Quartz 、Fused silica、OHARA、SCHOTT and customer designated materials.
Surface flatnessλ/4@ 633nm
Surface Quality40-20 S/D
CoatingPolarization splitting coating and AR-coatings see details in Coating service page.
The beam splitter cube and prism split the light into two beams while avoiding changes in beam position and phase.
Polarizing Cubes for Medium Power Applications Each beamsplitter consists of a pair of high precision tolerance right angle prisms cemented together with a dielectric coating on hypotenuse of one of the prisms. Typical damage threshold of these cubes is >0.3 J/cm2 @ 1064 nm 10 ns at 20 Hz. Polarizing Cubes for High Power Applications Optically contacted polarizing beamsplitter cubes used for high power applications can withstand energy fluencies up to 10 J/cm2 @ 1064 nm 10 ns at 20 Hz.
