Most of the photochemical experiments need to simulate sunlight. Our xenon light source has a spectrum similar to sunlight, and the output wavelength range is 200~2200nm. The xenon lamp system is a high-power full-band light source with continuous wavelength distribution. Imported xenon lamp bulbs and leading module cooling technology are used to ensure concentrated and stable output of light energy. The high-efficiency coupling SMA905 interface output is convenient for the effective use of light in the test.
