据报道,一种专为荧光光谱和拉曼光谱等高灵敏度应用而设计的 CCD 阵列的噪声性能大为改善,比现有光电二极管阵列好40倍,通用电气公司 Reticon 分公司应用工程师 PaulGallagher 最近介绍了这种 RA0564J 型 CCD 阵列。光谱仪所用的典型光电二极管在室温下最低噪声约为1500个电子,而这种新型 CCD 器件的最低噪声仅有35个电子,从而大大改
It has been reported that a CCD array designed for high sensitivity applications such as fluorescence and Raman spectroscopy has significantly improved noise performance over conventional photodiode arrays by 40 times and recently introduced by Paul Gallagher, Applications Engineer, General Electric Reticon Corporation This RA0564J type CCD array. The typical photodiode used in the spectrometer has a minimum noise of about 1,500 electrons at room temperature, whereas the new CCD device has a minimum of 35 electrons, which greatly changes
