Medium Pressure Mercury Lamp Spectrum

Unlike most other uv sources the medium pressure lamp mpl has a polychromatic spectral distribution from 190 nm up to the infrared spectrum.

Medium pressure mercury lamp spectrum.

Typical spectrum of a uv medium pressure lamp type hg for disinfection application the above spectrum is well suited for disinfection. Mercury lamps emit sufficient energy above 300 nm at only certain wavelengths which are very useful for monochromatic irradiation and so the spectrum can also be used as a point light source providing uniform irradiation. In medium pressure mercury vapor lamps the lines from 200 600 nm are present. Medium pressure mercury lamps produce characteristic bands at 313 and 365 nm.

In medium pressure mercury lamps a plasma that emits uv light is generated by applying electrical voltage. Uv medium pressure mercury lamp electrode quadripin base helios produces ultraviolet lamps made of quartz glass with wavelengths from 185 to 400 nm. High pressure mercury vapor lamps are commonly used for general lighting purposes. An electrode type medium pressure lamp consists of three major components.

In addition to disinfection another main application area is curing of printing ink or varnish. Aquafine medium pressure mp lamp spectrum aquafine mp lamps are considered to be polychromatic lamps due to their wide output spectrum. Metal halide adding doping elements metal halide that change the spectrum of ultraviolet radiation thus optimizing it for different possible applications. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm.

Analysis by gc ms showed that the total photodecomposition of butyl methoxy dibenzoylmethane had occurred. A quartz glass sleeve. Our production facility is designed to meet specific customer requirements to produce customized one off lamps as well as achieve consistent quality in mass production. They emit primarily in the blue and green.

With an average of 10x the power density per unit arc length aquafine mp lamps have significantly higher power compared to amalgam lp lamps. E lectrodes sealed into the end of the quartz sleeve. The distribution of energy over the wavelength ranges is depicted on the left. Near uv spectral range 380 200 nm and far uv spectral range 200 10 nm.

A f ill material typically argon and precisely dosed amount of liquid mercury. Ultraviolet light can be divided into two ranges. The resulting photodegradation products were identified by 1 h nmr spectrometry. Thus within the scope of the physical possibilities wavelengths can be selectively generated.

The mercury medium pressure uv lamps are appreciated mainly for two applications. The spectrum of uv medium pressure lamps can be influenced by doping graphic 5 6. They combine cure efficiency with design versatility and moderate cost. Butyl methoxy dibenzoylmethane was irradiated for 100 h in a quartz immersion well photoreactor equipped with a medium pressure mercury vapor lamp.

For uv curing and drying.
