The PLS-SME400E H1 Xenon Lamp Light Source is a research-grade light source designed for photocatalysis (photochemistry), providing a strong spectral output from the ultraviolet to near-infrared regions. It is widely used in research fields such as photocatalytic water splitting for hydrogen production, photodegradation of pollutants, various simulated sunlight visible light acceleration experiments, and ultraviolet band acceleration experiments. This light source enables high energy density and long-term continuous irradiation. When combined with various filter sets, it allows both narrow-band catalyst performance evaluation and broadband overall catalytic effect evaluation. The product can be integrated with multiple reactors (systems) to perform online and offline analysis experiments in solid, liquid, and gas phases. It can also extend the research range to the solar spectrum beyond the atmosphere. Moreover, it features a compact xenon lamp housing design—the smallest of its kind in China—with outstanding versatility, flexibility, and mobility, meeting the needs of multi-directional illumination experiments in limited spaces. The light source housing adopts a non-metallic shell with high insulation resistance, ensuring operational safety.
