The flat spectrum holographic concave grating is a reflection grating made by the double beam interference method, mainly used for small flat spectrum instruments and fully automatic biochemical analysis instruments. The grating does not need to rotate and only needs to be incident through a narrow slit. The receiver is a CCD transistor array, and the spectral range can be from ultraviolet to near-infrared bands.
