HGILX500 high voltage xenon lamp light source is a research grade xenon lamp light source specially for solar cells. 500W (power adjustable) high voltage short arc spherical xenon lamp is installed inside the light source to form arc discharge under high frequency and high voltage excitation. High voltage short arc spherical xenon lamp is a point light source with small luminous point. When ignited, it radiates a strong and stable continuous spectrum from ultraviolet to near infrared. The light color in the visible region is very similar to sunlight, with high energy density and stable output. It is widely used in solar cell research, photoelectric response device testing, surface photovoltage spectrum, biological illumination, photocatalysis, surface defect analysis and other fields.
