Cube beam splitters are more versatile, often with 0-degree AOI. A beamsplitter is an optical device designed to divide a beam of light into two separate paths—one transmitted and one reflected. This is usually done by applying a thin-film coating on a glass substrate and angling the element relative to the incoming light. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Selecting the right component involves navigating trade-offs between power handling, polarization sensitivity, chromatic dispersion, and mechanical stability. Newport offers a wide variety of Beamsplitters in various shapes.
