Beamsplitters are used in laser systems, optical interferometry, fluorescence, and biomedical instrumentation. All are made using a partially reflecting coating, but due to differences in construction, they differ in. Beamsplitters are fundamental components in optical engineering, serving to precisely divide a single input beam of light into two distinct output beams. This division allows for the simultaneous analysis or utilization of the light's properties along two separate paths. These versatile tools can split both laser and regular light, depending on the application in question. They come in three basic forms: plate, pellicle, and cube.
