【English Version】
FM-ZP4 Photoelectric Effect Experimental Apparatus is a precision optical instrument specifically designed for physics education in higher education institutions. Based on the classic photoelectric effect principle, this modular-structured device enables students to independently explore the relationship between photoelectron kinetic energy, incident light frequency, and intensity, thereby verifying the core theories of Einstein s photoelectric equation. Equipped with a high-stability light source system and low-noise signal acquisition module, the apparatus accurately measures cut-off voltage and photocurrent characteristic curves of metallic materials under monochromatic light irradiation across various wavelengths.
The system comprises three core functional modules: The multi-band adjustable light source provides visible to near-ultraviolet light ranging from 365nm to 650nm, with precision filters ensuring accurate wavelength control. The phototube measurement module features low dark-current design and programmable voltage regulation (0-30V continuous adjustable reverse voltage). The open experimental architecture allows users to interchange photocathodes with different work functions, facilitating comparative studies on material properties. A 7-inch touchscreen displays real-time photocurrent-voltage curves and key parameters, dynamically visualizing experimental processes.
Designed with pedagogical practicality, the apparatus integrates full-shielding optical paths to eliminate ambient light interference, while its aluminum alloy base with triple shock-absorbing pads ensures measurement stability. The included PC software supports USB/Bluetooth dual-mode data transfer, automatically generating experiment report templates and exporting data in multiple formats. Ideal for courses like "University Physics Experiments" and "Modern Physics Experiments", it effectively demonstrates quantum concepts including light particle behavior and energy quantization, significantly enhancing students comprehension of fundamental quantum mechanics principles.
