UV Lamps
There is a wide range of lamp types available on the market. In industrial applications we differentiate between the following four types of UV lamps:
Mercury lamps (Hg lamps); we differentiate between
- Mercury low-pressure lamps
- Mercury medium-pressure lamps and
- Mercury high-pressure lamps
These bulbs are delivered as pure mercury lamps or as doped lamps. Doping materials include for example iron (Fe), gallium (Ga) or other substances; this enhancement is responsible for the emission spectrum of the bulb.
In addition we differentiate between lamps with and without electrodes.
- Excimer Lamps
- UV Lasers
- UV LED's
In industrial applications the pure mercury medium pressure bulb is the most commonly used bulb (> 90%). The length of the lamp may vary from a few centimeters up to more then two meters.
Low-pressure lamps are used for example in neon tubes, in cosmetic applications and in the field of security applications (testing banknotes and so on).
