The PL-X500D simulated solar xenon lamp light source is equipped with a 500W high-voltage short arc spherical xenon lamp inside, which forms arc discharge under high-voltage excitation. A high-pressure short arc spherical xenon lamp is a light source with a very small emitting point. When ignited, it emits a strong and stable continuous spectrum of light waves from ultraviolet to near-infrared. The visible light color and temperature in the visible region are very similar to sunlight, making it an ideal light source for simulating AM1.5G standard sunlight. It is not only used in solar cell research, but also in the testing of photoresponsive devices, surface photovoltage spectroscopy, bioluminescence, photocatalysis, optical detection, various simulated sunlight visible light acceleration experiments, surface defect analysis and other fields
