Research On The Theory And Device Of Grating Spectrome R

In the paper, we will thoroughly introduce and analyse all kinds of spectrometers, then its progress and important application. We mainly do the research on impact factors and improved measures of resolution. Compacted with typical spectrometers as Ebert-Fastie spectrometer, Czerny-Turner spectrometer and Aberration corrected concave holographic grating spectrometer, we are going to do detail research especially on their working theory, structural parameters and function, such as the source of stray light, the analysis of signal to noise ratio, the placing of detector, aberration's theory, aberration's caculation and it's elimination. Combined with Ebert-Fastie spectrometer, we conclude the equation caculating on the range of wave length. At the above foundation, we come into being the suggestion on the grating and spectrometer's struction, accounting for high function in the UV-VIS wave band. At last, we design a caculating software that can get the variety of function as resolution when changing kinds of parameters, against level symmetric Ebert-Fastie spectrometer by computer. The paper will give a new method for the research and device of spectrometers.
