Frequently Asked Questions

A plate beamsplitter is a device that divides incident light into transmission and reflection components.

Plate beamsplitters have applications in astronomy, biomedical, medical, communications, industrial, military, scientific research, and more.

The first surface of plate beamsplitters is coated with all-dielectric materials to yield the desired transmission and reflection characteristics. The second surface has an all-dielectric AR coating to eliminate secondary reflection.

Yes, the coating of plate beamsplitters can be optimized to meet your specification (R/T ratio, angle of incidence and wave length).

The requirement for a specific plate beamsplitter was 25%R, 75%T for average polarization @ 550nm on float @ 45°. This customer required a 50/50 ±5% split at 1.06µm and greater than 20% reflection in the visible at 45° for average polarization on BK-7.
