The PL-XQ500W simulated solar xenon lamp light source is a high-performance xenon lamp light source independently developed by our company. A 500W high-voltage short arc spherical xenon lamp is installed inside the lamp head, 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, which emits continuous light waves from ultraviolet to near-infrared when ignited, and has a stable output. The visible light color temperature is similar to sunlight, making it an ideal light source for simulating AM1.5 standard sunlight. It is widely used in photocatalysis, photodegradation, solar cell research, and optoelectronic responsive device testing.
