The application of photoelectric technology in the fields of research, industry, and testing continues to deepen - photovoltaic cell research strives for "precise spectral replication", material aging tests require "stable full-spectrum irradiation", photoelectric catalysis relies on "high-intensity uniform light source", while traditional xenon light sources generally face four major pain points: "incomplete spectral purity, poor stability, short lifespan, and difficult heat dissipation": ordinary xenon light sources have a spectral matching degree of less than 80%, light intensity fluctuation exceeds ±1%/h, lifespan is only 3000 hours, and severe temperature attenuation makes them unable to meet the precise requirements of high-end scenarios; imported high-end xenon light sources cost over 200,000 yuan, the customization period is up to 3 months, and the core technology blockade leads to high maintenance costs.
Beijing Saifan Optoelectronics has been deeply engaged in the research and development of core components of photoelectric technology, supported by 28 light source-related patents, and has launched the 7ILXC300 series of high-performance xenon light sources. By leveraging "full-spectrum precise replication, millisecond-level stable output, long lifespan with low attenuation, and universal scene adaptation" four core technologies, it redefines the standard of high-end xenon light sources and becomes the "core light power" in fields such as scientific research experiments, industrial testing, and environmental simulation, providing top-level light source solutions for solar simulators, aging test chambers, photoelectric catalysis systems, etc.
1. Core Technology One: Full-spectrum Precise Replication Technology - Full coverage of 280-2500nm, matching degree 99.2%
Traditional xenon light sources have problems such as the absence of ultraviolet bands and rapid attenuation of infrared bands. The 7ILXC300 adopts "space-grade short arc xenon lamp + multi-band filter optimization technology" to achieve full-spectrum precise coverage from deep ultraviolet to near-infrared:
