Plate Beam Splitters: These are usually positioned at a 45° angle of incidence (AOI) relative to the incoming light beam. This orientation allows the plate to reflect a portion of the light at 90° while transmitting the remainder along the original path. Anti-reflective coatings on the back surface and optional compensation plates are often used to minimize ghost reflections and match optical path lengths in sensitive applications . Cube Beam Splitters: Cube splitters are generally placed in line with the optical axis at 0° AOI. One output beam continues along the original axis, while the other is deviated 90° due to the internal prism interface. This placement reduces beam offset caused by refraction and helps maintain alignment in interferometers and laser systems . Pellicle Beam Splitters: These thin, tensioned membranes are placed directly in the beam path, often at 45°, to minimize chromatic dispersion and eliminate ghost reflections. Their delicate construction makes them suitable for low-power, high-precision applications where minimal optical distortion is critical .
