How much light does a beam splitter produce

Typically made of glass, a beam splitter divides the light passing through it at a ratio. Usually, half of the light is reflected at an angle, and the other half is transmitted to the opposite side of the light source. 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. This division allows for the simultaneous analysis or utilization of the light's properties along two separate paths. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux).
