Abstract

A multi-function grating spectrometer is introduced, which is composed of grating monochromator, signal receiving units, electronic amplifiers, A/D converter, computer, matching illuminant and so on. This equipment is a complex technique related to optics, precision machinery, electronics and computer. CCD and optical grating is used that break the limitation of photomultiplier (PMT). The CCD can receive signals in the spatial distribution. The efficiency of full spectrum detection is greatly raised. With the way of DMA block move and adopting high-speed A/D AD1674JN it realizes high-speed data acquisition. The principles of system working, hardware circuit, logic of controlling are described in detail. The spectrometer has two kinds of measurement range, the CCD can measure the spectrum wave from 300 nm~600 nm, and the photomultiplier (PMT) can measure the spectrum wave from 200 nm~660 nm. Controlling a Step Motor that cooperating with a deceleration system, and using the C-T optical system, in theory, moving 0.01 nm can catch a spectral pulse, the resolution can reach 0.06 nm.
