How Are Uv Lights Made

One of the most common ways of producing UV light is passing an electric current through vaporized mercury or some other gas. This type of lamp is commonly used in tanning booths and for disinfecting surfaces. The lamps are also used in black lights that cause fluorescent paints and dyes to glow.

How is ultraviolet light produced?

UV radiation is produced either by heating a body to an incandescent temperature, as is the case with solar UV, or by passing an electric current through a gas, usually vaporized mercury. The latter process is the mechanism whereby UV radiation is produced artificially.

Can we create ultraviolet light?

If you want to take a white LED and get UV light, you just need to block the visible colors while leaving the UV light to pass through. There are some materials—like fused quartz or fluorite that do exactly this and can be used to make some pretty cool UV photographs.
