PLS-SME400E H1 Xenon Light Source is a research-grade light source for photocatalysis (photochemistry), providing intense spectral output from ultraviolet to near-infrared regions. Widely used in research areas such as photocatalytic hydrogen production, photodegradation of pollutants, various simulated sunlight visible light accelerated experiments, and various simulated sunlight ultraviolet band accelerated experiments. The light source can achieve high energy density and long-term continuous irradiation. When combined with various filter combinations, it can achieve narrow-band catalyst improvement effect evaluation and overall broadband catalytic effect evaluation. This product can be used with various reactors (systems) to complete online and offline analysis experiments in solid, liquid, and gas phases. This series of light sources can expand the research scope beyond the Earth's atmosphere solar spectrum.
