UV light source of UV Aging Test Chamber

◆ The commonly used UV lamps mainly include UV-A 340 and UV-B 313

◆ UV-A-340 is the best choice for simulating the ultraviolet rays of sunlight. It can perfectly simulate the sunlight spectrum in the critical short-wavelength range (closer to the solar spectrum), that is, the spectrum in the wavelength range of 295-360nm, UVA-340 only Produces a spectrum of UV wavelengths that can be found in sunlight.

◆UV-B-313 simulated sunlight ultraviolet aging intensity is greater than UV-A, and the damage intensity is much greater than UV-A. It is suitable for the maximum degree accelerated UV aging test, and it can quickly provide test results. The short-wavelength UV it uses is stronger than the UV light waves commonly found on the earth. Although these UV light, which is much shorter than the natural wavelength, can accelerate the test to the greatest extent, it can also cause inconsistency and actual degradation of certain materials.
