Problems solved by technology

However, spectral analysis technology has high requirements on the spectral transmission characteristics of the optical system, especially in the ultraviolet spectral range, because ultraviolet light is easily absorbed during transmission, the transmission loss is large, and the transmission process is easily disturbed by the outside world
However, the traditional optical system design in the prior art cannot meet the requirements of ultraviolet spectroscopic process analysis
