Basic configuration offers one UV and one white light tube -- the advantage of white light or UV illumination from one unit! Use white light when working with materials in a dimly-lit area.Twin models have two tubes of the same wavelength or the 2UV™ Models use two different wavelengths...

Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. On interaction with...
athe wavelength range of UV radiation starts at the blue and of visible light(about 400 nm) and ends at approximately 200 nm for spectrometers operated in air 正在翻译,请等待...[translate]
Pete’s Luminous Creations offers a range of products that will illuminate your surroundings. Glow in the Dark products have the remarkable ability to absorb surrounding light and store it, so when it’s dark, they emit a captivating glow. This is why they are appropriately named Glow in the...
UV- light pulses in the range of 290 to 400 nm strongly induce the expression of Cat2. Upon removing the UV-B portion (290-310 nm) of the UV-spectrum the maximal Cat2 transcript level was reduced by about 60%. On applying UV-light of the same quality in addition to visible light,...
"Far-UVC light has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye, so it's not a human health hazard," said Brenner. "But because viruses and bacteria are much smaller than human cells, far-UVC light can reach ...

Ultra-violet (UV) light has still a limited scope in optical microscopy despite its potential advantages over visible light in terms of optical resolution and of interaction with a wide variety of biological molecules. The main challenge is to control in a robust, compact and cost-effective way...
Five groups of guinea-pigs were used to test the effect of various spectral bands of solar-simulated light on low-dose DMBA-induced melanocytic nevi. Animals were irradiated with either UVB to near UVA2 (290–325 nm), UVA, visible light, full solar spectrum or no irradiation three times ...
