The function of the dichroic mirror filter is to provide different transmittance and reflectivity for incident light of different wavelength bands. Two-color beam splitters can be used to combine or separate light waves of different colors. The dichroic mirror has high transmittance to light below the cut-off wavelength, and high reversibility to light beams above the cut-off wavelength. This product is a long-wave transmission dichroic mirror with high reflectivity for light beams below the cut-off wavelength, and high transmittance for light beams above the cut-off wavelength. The dichroic mirror produced by Ruicheng Optoelectronics has a variety of medium wavelengths to choose from. Such optical elements can also be used to combine light beams with a wavelength (or wavelength range) smaller than the wavelength (or wavelength range) with light beams (or wavelength range) larger than the wavelength.
Often used in laser technology
Its characteristic is that the light of a certain wavelength is almost completely transmitted, while the light of other wavelengths is almost completely reflected.
