Beam Splitter Flat
PRODUCT CATEGORIES
INOUIRY
Beam splitters are usually used at a 45° tilt, with one side coated with a beam splitter film and the other side coated with an anti-reflection film. They can split the incident light into two parts: reflected light and transmitted light.
The front surface of the beamsplitter is coated with a beam splitter film, and the back surface is usually coated with an anti-reflection film to reduce the interference effect between beams and ghost images. Beam splitters are light in weight, moderately priced, and relatively easy to make. Beam splitters are an optical component that can split a radiation beam into several parts.
We provide a variety of broadband beam splitters with beam splitter films on the front surface and VIS, NIR, and SWIR anti-reflection films on the back surface.
