From August 3 to 7, 2026, the 13th China National University Physics Experiment Teaching Symposium was successfully held in Deqing, Zhejiang. The symposium was organized by the Physics Teaching Steering Committee of the Ministry of Education, the University Physics Curriculum Teaching Steering Committee of the Ministry of Education, and the National Society for University Physics Experiment Teaching, co-hosted by Zhejiang University of Technology and Zhejiang Physical Society. A total of 446 faculty members and students from 145 universities across China, along with representatives from nearly 40 instrument manufacturers, attended this premier academic event in the field of physics experiment teaching.
During the concurrent Self-Made Physics Teaching Instrument Competition, the Diffraction-Grating-Based Photoelectric Effect Apparatus, jointly developed by Brolight and Southeast University, was awarded First Prize in the General Physics Experiment Group. The competition received 158 entries from 70 universities. After a rigorous three-stage evaluation process—initial paper review, on-site presentation and review, and final defense—39 first-prize, 73 second-prize, and 40 third-prize winners were selected.
About the Competition
The Self-Made Physics Teaching Instrument Competition is organized by the National Society for University Physics Experiment Teaching and is held biennially. The competition evaluates instruments developed by university faculty and students for physics experiment teaching, with strict requirements on teaching innovation, technical advancement, and promotion feasibility.
Core evaluation principles include:
● The instrument must be physically sound and demonstrate innovation
● "Modular" instruments are encouraged; "black-box" instruments are discouraged
● The instrument must demonstrate good repeatability and stability with effective teaching outcomes
● Commercialized instruments are expected to have a certain market share and positive user feedback
Brolight Wins First Prize for Two Consecutive Sessions
Following the First Prize won by the BEX-8508C P-type/N-type Hall Effect Apparatus, jointly developed by Brolight and Southeast University, at the 12th session in 2024, the BEX-8518 has once again received First Prize in the General Physics Experiment Group at this session. Winning this honor for two consecutive sessions marks the continued high recognition of Brolight's product R&D capabilities and teaching philosophy by experts in the field of university physics experiment teaching nationwide.
In addition, at this session, the "AI Model-Based Intelligent Assistance System for Franck-Hertz Experiment", jointly developed by Zhejiang University of Technology and Brolight, won Second Prize in the Modern Physics Category, further demonstrating Brolight's cutting-edge exploration in the intelligentization of physics experiment teaching instruments.
Product Highlights: Diffraction-Grating-Based Photoelectric Effect Apparatus
The Diffraction-Grating-Based Photoelectric Effect Apparatus BEX-8518 is a new-generation comprehensive photoelectric effect experiment system developed by Brolight for university fundamental physics experiment teaching. Its core advantages include:
1. Continuously Tunable Monochromatic Light Output
Traditional equipment relies on mercury lamp characteristic spectral lines and bandpass filters, providing only 5 discrete wavelengths (365, 405, 436, 546, 577 nm). The BEX-8518 employs a reflective diffraction grating monochromator integrated with a dual light source system (low-pressure mercury lamp and broadband LED), achieving continuously tunable wavelength output covering the visible spectrum.
2. Open Optical Path Design
All optical components are mounted on a precision optical breadboard with a fully open and visible optical path. Students can directly observe the complete optical train—collimation, dispersion, and focusing—of the grating monochromator, eliminating the "black box" limitations of traditional enclosed monochromators.
3. Simultaneous Verification of Wave-Particle Duality
The same apparatus enables both grating diffraction (wave nature) and photoelectric effect (particle nature) experiments, systematically verifying the wave-particle duality of light and helping students develop a complete understanding of the nature of light.
4. Rich Experimental Content
Covering 6 major experiment modules: grating diffraction observation, wavelength calibration, current-voltage characteristic measurement, spectral response testing (continuous wavelength scanning), photocurrent vs. light intensity investigation, and stopping potential vs. frequency investigation, supporting progressive, multi-level teaching.
The BEX-8518 is a brand-new grating-based photoelectric effect comprehensive experiment apparatus developed by Brolight on the foundation of the BEX-8504 series filter-based photoelectric effect apparatus. While retaining the data acquisition and analysis advantages of its predecessors, it upgrades the dispersion method from discrete filters to continuous grating spectroscopy, expanding experimental content from basic Planck's constant determination to inquiry-based experiments including spectral response characterization and wave-particle duality verification—achieving a teaching upgrade from a "verification-type" apparatus to an "inquiry-type" platform.
