-Instrument Introduction

The main box of SGY-3 photoelectric detection principle comprehensive experimental instrument is the standard part, and the packaging of photoelectric devices is the optional part. Inside the main box, half of the circuit PCB board and half of the optical path components are placed inside the main box. This not only allows students to have a clear understanding of the optical circuit of the entire experimental system, enhances their understanding of the system, but also is aesthetically pleasing and easy to carry and store. In the circuit PCB board section, modular design is adopted, including light source driving unit, pulse driving unit, signal testing unit, light source indicator unit, etc.
