This interactive tutorial explores transmission and reflection of a light beam by three common beamsplitter designs. A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. In its. π¦ For purchasing, use the RP Photonics Buyer's Guide for beam splitters. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. All are made using a partially reflecting coating, but due to differences in construction, they differ in power handling.
