How does a beam splitter workdiagram

The key to the functionality of a beam splitter lies in the reflective coating. For a 50/50 beam splitter, the coating is engineered to reflect half of the light intensity and allow the other half to pass through. When a light beam strikes the coating, the beam splitter's dielectric material properties, along with the thickness and composition of the coating, determine the specific reflection/transmission characteristics.

A 50/50 beam splitter is an optical device that divides an incoming light beam into two equal parts. The designation '50/50' refers to the splitting ratio of the transmitted to reflected light, implying that 50% of the incident light is transmitted and 50% is reflected.

Beam splitters are made from glass or other optical materials and can come in different forms such as cube or plate. A cube beam splitter is typically created by joining two right-angled prism halves at their hypotenuse with a dielectric or metallic coating layer between them. This layer is designed to split the light evenly. A plate beam splitter, on the other hand, is a thin flat piece of glass with a partially reflective coating on one side.

In interferometers, 50/50 beam splitters are used to split a coherent light source into two paths which later recombine to produce interference patterns. These patterns provide information regarding the optical path difference between the two paths, which is used for precise measurements of distance or changes in refractive index.

Accordingly, 50/50 beam splitters are integral components in various optical systems where splitting light with high precision is crucial to the operation or measurement being undertaken.
