Qu'est-ce qu'un rayonnement ultraviolet, comment cela fonctionne-t-il, est-ce dangereux pour la santé Where critical process parameters are required for UV cure processes, a radiometer can ensure your process remains consistent by accurately measuring the Wavelengths shorter than 280 nm fall into the UVC spectrum. Neither Vernier sensor is sensitive to UVC radiation. Plants and animals respond differently to the In many articles pollutants are being degraded by UVA rays, why UVA? What would be the impact if instead UVB or UVC was used? Is there any literature data The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). UVA rays penetrate deep 7.

また、人間の健康や環境への影響の観点から、近紫外線をさらに UVA (400–315 nm)、 UVB (315–280nm)、 UVC (280 nm 未満) に分けることもある uva进一步分为两个波段，uva i，测量340-400纳米（nm，或十亿分之一米），uva ii，从320-340纳米。uvb的范围为290至320nm。对于更短的射线，大多数uvc被臭氧层吸收并且不会到达地球。 UVA: 320-400 (nm) UVB: 290-320 (nm) UVC: 200-290 (nm) Since all of these UV rays are shorter than or equal to 400 nm, they are blocked by the lenses - keeping your eyes safely protected. This also explains why you can still see color. The color red has a wavelength of 680 nm. Since it is greater than 400 nm, it is not blocked by the UV 400 lenses.

UVA, UVB, UVC, and UVV? UV curing is a photochemical process that generally uses multiple UV wavelengths depending on the process requirements. These wavelengths each travel different distances through the substrate being cured. The UV ranges are named … UVB, UVA and UVC rays are all part of the ultraviolet light that travel towards earth from the sun. UVC rays are absorbed by the ozone layer, so you don’t have to worry about them.

UVB – Medium-wavelength UVB covers the range 280–315 nm. Approximately 10% of UV radiation reaching the Earth’s surface.

UVA, UVB, UVC- all of these are forms of ultraviolet light rays that are naturally occurring, but they are not created equal. We'll explain the differences between these three forms of radiation, and then discuss how UVC is harnessed in man-made lighting products to inactivate pathogens (kill germs).
