Ultraviolet lamp is a kind of light source that can produce ultraviolet rays in a large effective range. In fact, there are often ultraviolet rays in more general light sources, and the sun is the most obvious. As far as general tungsten lamps are concerned, there is about 320nm near ultraviolet light in the possible range of ultraviolet light transmitted by glass, and it can be further if quartz bulbs are used. Hydrogen lamp or xenon lamp can obtain further ultraviolet light, which is suitable for the range of 400 ~ 190 nm. In addition, there are helium lamps and krypton lamps.
