Frequently Asked Questions

Cube or plate beamsplitter?

Cubes have no beam offset and are easy to align at normal incidence. Plates are lighter and cheaper and are used at 45°, but shift the transmitted beam and can create a ghost reflection.

What extinction ratio do your PBS reach?

Up to 3000:1 for the broadband PBS cube and narrow-band PBS plate.

Which split ratios are available?

Standard R:T ratios are 10:90, 30:70, 50:50, 70:30 and 90:10; custom ratios are possible.

What wavelength ranges do you cover?

PBS from 300 to 2000 nm; NPBS cubes and plates in bands between 350 and 1700 nm, or custom.

What is an array NPBS plate?

A plate that splits one beam into several parallel beams of set intensity, useful for multi-channel optical systems.
