The PL-X300DF large spot simulated sunlight xenon lamp light source is an ideal light source for simulating sunlight. The light source is equipped with an imported 330W high-voltage short arc xenon lamp, which forms arc discharge under high-frequency and high-voltage excitation. High voltage short arc spherical xenon lamp is a point light source with a very small emission point. When ignited, it emits strong and stable light waves, with a strong continuous spectrum from ultraviolet to near-infrared, and stable output. It is widely used in photocatalysis, industrial catalysis, photocatalytic hydrogen production, photoelectrochemical catalysis, photochemical synthesis, photodegradation of pollutants, water pollution treatment, biological illumination, optical detection, and various simulated sunlight visible light accelerated experiments
