摘　　要：建立了一种普通荧光分光度计增加波长扫描功能的简易方法。利用光纤传感器、光纤放大器识别荧光分光光度计波长刻度盘上的刻度线,使光纤发出的光束每经过一条刻度线时就产生一个脉冲信号,从而建立起波长信号与荧光值检测信号之间的联系,实现波长扫描功能。方法简便实用,可以应用于带有波长刻度盘及配套数据处理软件的荧光光度计、紫外-可见分光光度计的改装。A simple method for adding wavelength scanning function to ordinary photometers was established.By using fiber optic sensor and amplifier to identify the scale lines on wavelength dial of photometer,a pulse signal was generated every time the light beam emitted by the fiber passes through a scale line,thereby establishing the connection between the wavelength signal and the fluorescence signal,and achieving the wavelength scanning function.The method is simple and practical,and can be applied to the modification of fluorescence photometers and UV-visible spectrophotometers which possessing wavelength scales and supporting data processing software.
