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.

These lamps also called mercury arc lamps are the workhorse of the light curing industry. In medium pressure mercury lamps a plasma that emits uv light is generated by applying electrical voltage. Ultraviolet light can be divided into two ranges. For uv curing and drying.

Thus within the scope of the physical possibilities wavelengths can be selectively generated. A f ill material typically argon and precisely dosed amount of liquid mercury. A quartz glass sleeve. In addition to disinfection another main application area is curing of printing ink or varnish.

Mp lamps operate at roughly 800 c 900 c. The resulting photodegradation products were identified by 1 h nmr spectrometry. Near uv spectral range 380 200 nm and far uv spectral range 200 10 nm. 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. Uv medium pressure mercury lamp electrode quadripin base helios produces ultraviolet lamps made of quartz glass with wavelengths from 185 to 400 nm. Butyl methoxy dibenzoylmethane was irradiated for 100 h in a quartz immersion well photoreactor equipped with a medium pressure mercury vapor lamp. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm.

They combine cure efficiency with design versatility and moderate cost. 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. Typical spectrum of a uv medium pressure lamp type hg for disinfection application the above spectrum is well suited for disinfection. An electrode type medium pressure lamp consists of three major components.

High pressure mercury vapor lamps are commonly used for general lighting purposes. Medium pressure mercury lamps produce characteristic bands at 313 and 365 nm. Aquafine medium pressure mp lamp spectrum aquafine mp lamps are considered to be polychromatic lamps due to their wide output spectrum. They emit primarily in the blue and green.

Analysis by gc ms showed that the total photodecomposition of butyl methoxy dibenzoylmethane had occurred. E lectrodes sealed into the end of the quartz sleeve. With an average of 10x the power density per unit arc length aquafine mp lamps have significantly higher power compared to amalgam lp lamps. The distribution of energy over the wavelength ranges is depicted on the left.

The mercury medium pressure uv lamps are appreciated mainly for two applications.
