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. They are formed on the glass surface through ion beam-assisted evaporation coating, enabling transmission of red and green light while reflecting blue wavelengths. The coating 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.
