It has strong penetrating power and can penetrate most transparent glass and plastic. More than 98% of the long-wave ultraviolet rays contained in sunlight can penetrate the ozone layer and clouds to reach the earth's surface. UVA can reach the skin's dermis, destroy elastic fibers and collagen fibers, and tan our skin. UVA with a wavelength of 360nm conforms to the phototaxis response curve of insects, which can be used to make insect traps. UVA with a wavelength of 300-420nm can pass through a special colored glass tube that completelycuts off visible light. It only emits near-UV light centered at 365nm. It can be used for ore identification, stage decoration, banknote detection and other places. UVB: Wavelength, wavelength 275 ~ 320nm, also known as medium wave erythema effectultraviolet. Medium penetration. Its shorter wavelength will be absorbed by transparent glass. Most of the medium-wave ultraviolet rays contained in sunlight are absorbed by the ozone layer, and only less than 2% can reach the surface of the earth. It will be particularly strong in summer and afternoon. UVB has erythema effect on the human body, can promote mineral metabolism and the formation of vitamin D in the body, but long-term or excessive irradiation will tan the skin and cause redness and peeling. Ultraviolet health care lamps and plant growth lamps are made of special violet-transparent glass (which does not transmit light below 254nm) and phosphors with a peak around 300nm UVC: Ultraviolet UVC wavelength, 200 ~ 275nm, also known as short-wave sterilization ultraviolet. Its penetrating ability is the weakest and cannot penetrate most of transparent glass and plastic. The short-wave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer. Short-wave ultraviolet rays are very harmful to the human body. Short-term exposure can burn the skin. Long-term or high-intensity exposure can also cause skin cancer. Ultraviolet germicidal lamps emit short-wave UVC. UVD: Wavelength, wavelength 100 ~ 200nm, also known as vacuum ultraviolet.
