摘　　要：针对光电信号转换特性的测量实验仪存在的不足,对仪器的螺杆传动结构、暗箱结构、读数结构及更换器件部分做了创新性设计.该仪器能在正常的环境光照条件下做实验,较准确地读出光电转换器件间的变化距离(精度可达到0.01 mm),更能方便地更换研究的器件.To overcome the shortcomings of conventional experiment apparatus of measuring photoelectricity transformation characteristics, this paper focuses on the design and making of a new experimental apparatus. The structure and usage methods of the apparatus are expounded. The new apparatus has three features： easy replacement of different devices, convenient and precise measurement of the distance between light-emitting device and receiving device, operation in normal indoor light.
