Problems solved by technology

[0010] However, grating spectrometers using photomultiplier tubes or CCDs as photodetectors need to convert optical signals into electrical signals, and then use computers and other equipment to perform subsequent processing on spectral information such as electrical signals. Influenced by the conversion of signals into electrical signals, general photomultiplier tubes or CCDs can only respond to shorter wavelength ranges within the spectral wavelength range of 200-1100nm, and cannot simultaneously meet the data collection of spectral wavelength points for larger spectral wavelength ranges.
