LRGB filters correspond to brightness, red, green and blue channels respectively, and the RGB ratio is basically 1:1:1, which can realize color separation. It is mainly used for deep space photography and planetary photography of astronomical CCD, which is more simple and convenient in post-processing. High quality optical glass is adopted to ensure good parallelism of the lens. High quality double-sided multi-layer coating process can effectively suppress infrared interference, have excellent transmittance, and accurately restore the color to perfectly meet the SRGB color standard.
