Measurement of Photoelectric Characteristics of Photosensitive Sensors

This photoelectric characteristics experiment system is designed to study the electrical and optical behavior of various photosensitive devices. It enables students to measure the voltage-current and illumination characteristics of silicon photocells, photoresistors, photodiodes, and phototransistors using precision measuring instruments.
