How many paths can a beam splitter split at most
At its essence, a beam splitter is a device that can direct light into two unique paths. When a light beam comes into contact with these cubes, half of it enters the glass, while the other half is reflected. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Thus, multiple configurations are needed to trace rays along both the transmitted and reflected paths within the beam splitter.
