Medium Pressure Mercury Lamp Spectrum

Thus within the scope of the physical possibilities wavelengths can be selectively generated.

Medium pressure mercury lamp spectrum.

Mp lamps operate at roughly 800 c 900 c. A quartz glass sleeve. Near uv spectral range 380 200 nm and far uv spectral range 200 10 nm. For uv curing and drying.

Typical spectrum of a uv medium pressure lamp type hg for disinfection application the above spectrum is well suited for disinfection. Uv medium pressure mercury lamp electrode quadripin base helios produces ultraviolet lamps made of quartz glass with wavelengths from 185 to 400 nm. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm. With an average of 10x the power density per unit arc length aquafine mp lamps have significantly higher power compared to amalgam lp lamps.

Medium pressure mercury arc ushio produces standard and custom uv emitters. Butyl methoxy dibenzoylmethane was irradiated for 100 h in a quartz immersion well photoreactor equipped with a medium pressure mercury vapor lamp. The resulting photodegradation products were identified by 1 h nmr spectrometry. Metal halide adding doping elements metal halide that change the spectrum of ultraviolet radiation thus optimizing it for different possible applications.

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. E lectrodes sealed into the end of the quartz sleeve. A f ill material typically argon and precisely dosed amount of liquid mercury.

In addition to disinfection another main application area is curing of printing ink or varnish. They emit primarily in the blue and green. High pressure mercury vapor lamps are commonly used for general lighting purposes. Ultraviolet light can be divided into two ranges.

They combine cure efficiency with design versatility and moderate cost. An electrode type medium pressure lamp consists of three major components. The spectrum of uv medium pressure lamps can be influenced by doping graphic 5 6. 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. 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. In medium pressure mercury lamps a plasma that emits uv light is generated by applying electrical voltage. Unlike most other uv sources the medium pressure lamp mpl has a polychromatic spectral distribution from 190 nm up to the infrared spectrum.

These lamps also called mercury arc lamps are the workhorse of the light curing industry.
