Miniaturization Development of UV-Vis Spectrophotometer and Key Techniques

In this paper, the miniaturization tendency of UV-Vis spectrophotometers and the key techniques on how todesign miniaturized UV-Vis spectrophotometers are introduced. The modern miniaturized UV-Vis spectrophotometer basedon multichannel detectors (CCD,MOS Image Sensor) and the traditional UV-Vis spectrophotometer based on singlechanneldetectors (PMT) are analyzed and compared. The results show that the miniaturized multichannel UV-Vis spectrophotometeris better than traditional UV-Vis spectrophotometer on SNR, sensitivity, measurement speed and mechanical structure, and issomewhat worse on spectral band width. According to the analytic result, the future work is put forward.
