Dichroic mirrors, also known as RGB beam combiners or laser beam splitters, are produced by Mingyuan Optoelectronics with an incident angle of 45 degrees ±5 degrees. The coating is formed on the glass surface using ion beam-assisted evaporation deposition, enabling transmission of red and green light while reflecting blue wavelengths. The film layer is robust and reliable, capable of withstanding high and low temperature cycle tests.

Application fields: DLP projectors, laser projectors, endoscopic cold light source systems, stage lighting, various types of lasers, etc.
