The PLS-SME300E H1 xenon lamp light source provides strong light output from the ultraviolet to near-infrared range. The overall housing is made of a non-metallic shell with high insulation resistance, ensuring the safety of the xenon lamp light source. Additionally, the compact size of the housing provides strong versatility, flexibility, and portability, meeting the requirements for multi-directional irradiation experiments in small spaces.
The PLS-SME300E H1 xenon lamp light source is widely used in research areas such as photocatalytic water splitting for hydrogen/oxygen, photocatalytic full water decomposition, photocatalytic CO2 reduction, and photocatalytic degradation of pollutants.
The PLS-SME300E H1 xenon lamp light source can achieve high energy density and long-time continuous irradiation. It can be used with various reaction systems to conduct online and offline analysis experiments in solid, liquid, and gas phases.
The PLS-SME300E H1 xenon lamp light source has two operating modes:
1. Electric control mode, i.e., constant current mode, where the power supply power for the xenon lamp is kept constant;
2. Light control mode, i.e., constant light irradiance mode, where the light intensity output of the xenon lamp is monitored in real-time based on the set light intensity value. It uses a built-in optical feedback module to automatically adjust the light intensity, maintaining the average irradiance within the set value over relative time, improving the accuracy of photocatalytic experiments.
