The experiments of photocatalysis, photoelectrochemistry and photoluminescence cannot be carried out without a continuous spectrum, stable output and precisely controllable simulated sunlight. The Sefan Optoelectronics 7ILX150P/7ILX500P photocatalytic xenon lamp is specially designed for catalytic research. It has a full-spectrum output with enhanced ultraviolet effect, which can be used independently for photodegradation and photolysis water experiments, or connected to the 7ISW50 triple grating scanning monochromator and 7ID101 photomultiplier tube detector to form an integrated spectral characterization platform, completing the detection of catalyst optical properties and luminescence signals in one step.

The lamp is equipped with a German-imported ultraviolet-enhanced short-arc xenon lamp, with a spectral coverage of 200?2500nm (ultraviolet-visible-near-infrared), a color temperature of approximately 6000K, and a highly accurate spectral curve that closely matches natural sunlight. The ultraviolet band has sufficient energy, perfectly matching the light energy conditions required for photocatalytic reactions. The 7ILX150P and 7ILX500P dual-power versions are available, with high light energy density, enabling multiple times the output of solar light, significantly accelerating the catalytic reaction process. The built-in high-stability linear power supply ensures that the light intensity fluctuation is less than 2% during long-term continuous illumination, avoiding the discreteness problem of experimental data caused by lamp drift, and ensuring the reproducibility of catalytic activity comparisons and kinetic tests.

The optical path adopts a downward light emission design, suitable for photocatalytic reactors and sample pool placement habits; the light emission port integrates an adjustable diaphragm, with a light spot of φ2?42mm that can be continuously adjusted, compatible with a Φ50mm filter, and can be added with ultraviolet cutoff, infrared filter, and AM1.5G filter as needed, freely screening the target wavelength band to eliminate infrared thermal effects and avoid sample heating interference. The optimized reflector structure for light concentration improves the utilization of light energy, and combined with the delay air cooling system, it continuously dissipates heat after shutdown, protecting the xenon lamp and extending the lamp bulb lifespan. The high-voltage trigger is integrated in the lamp box, eliminating the risk of external high-voltage connection, making laboratory long-term continuous experiments more reassuring.

The modular optical path design can be flexibly expanded: it can directly irradiate samples to conduct photocatalytic degradation, CO₂ reduction, photolysis water production; it can also be connected to the 7ISW50 triple grating scanning monochromator to output monochromatic light after dispersion by the monochromator, used for photoelectrochemical PEC testing, material PL photoluminescence, spectral response testing, and the rear end is equipped with a 7ID101 photomultiplier tube detector to collect weak spectral signals, forming a complete domestic full-chain spectral testing system.

✅ Core application scenarios

Photocatalysis: pollutant photodegradation, photolysis water production, CO₂ reduction, photochemical synthesis, catalyst activity evaluation

Photoelectronic materials: PL testing of perovskite, thin films, two-dimensional materials, semiconductor spectral response, quantum efficiency QE detection

Simulated sunlight experiments: AM1.5G sunlight simulation, material weathering aging, biological lighting experiments

Optical calibration: spectral calibration of the lamp, building a steady-state spectral testing platform with a monochromator

Domestic self-developed optical system, installation and debugging are convenient, with strong compatibility of accessories, reducing the cost of building a research platform. The 7ILX series xenon lamps, as the "light emission core" of the entire spectral system, combined with the 7ISW50 triple grating monochromator and 7ID101 PMT detector, cover the entire process of material optical characterization, and are the preferred light source for universities, research institutes, and photovoltaic enterprises' photocatalysis and spectral laboratories.
