- Instrument Introduction
The main chassis of the SGY-3 Comprehensive Experiment Apparatus for Photoelectric Detection Principles is included as standard equipment, while the packaging of the optoelectronic components is optional. Inside the main chassis, the circuit PCB and the optical path components each occupy half of the space. This design not only allows students to clearly see the entire optical circuit of the experimental system at a glance, thereby enhancing their understanding of the system, but also ensures an aesthetically pleasing appearance and convenient portability and storage. The circuit PCB section features a modular design, including a light source drive unit, a pulse drive unit, a signal testing unit, and a light source indicator unit.
