Grating spectrometer is the more advanced spectral measurement and analysis instruments, is currently the most commonly used spectral measurement
instruments, simple operation, convenient, accurate and widely used.
Grating spectrometer is widely used in spectral measurement, spectral that is decomposed polychromatic light into monochromatic light. But many grating
spectrometer still use manual adjustment fixed-point measurement mode of grating wavelength’s changes, This way of measurement has two prominent
shortcomings: the speed of measurement is slow, operating is troublesome, We let grating monochromatic connect to a computer, compose into
automatic measurement system of spectrum, it improved speed of the spectral measurement greatly, and make the measuring operation become simple
and convenient, and improved the overall performance of the system and application scope.
