PLS-FTC five point method photometric power density component Introduction: Due to the uneven distribution of optical power density in the output spot of the xenon lamp light source, it is necessary to measure the optical power density by selecting five points in the circular spot, and calculate the average optical power density using a formula for numerical calculations such as quantum yield. The PLS-FTC five point method photometric power density module is designed based on the measurement method of circular spot optical power density in "Energy Conversion Efficiency and Quantum Yield Calculation of Solar Photocatalytic Water splitting Hydrogen Production System" (GB/T 26915-2011). The PLS-FTC five point method photometric power density component is mainly used for precise positioning of five point irradiance testing, while avoiding interference from other measurement points, making the test data more accurate. characteristic: 1. Adopting a sliding card slot design, it is easy to operate and can be quickly and accurately positioned; 2. It has a light guide tube structure, which can effectively avoid stray light and interference from other measurement points; 3. It can directly measure the optical power density of the optical port, and can also be equipped with an extension tube to measure the optical power density of the actual working surface; 4. The length of the extension tube can be adjusted within a range of 8-12 cm; 5. Can be matched with PL-MW2000 strong light power meter, PM100D+S425C imported light power meter, FZ-A domestic irradiation meter.
