The distribution of energy over the wavelength ranges is depicted on the left.
Medium pressure mercury lamp spectrum.
For uv curing and drying.
They combine cure efficiency with design versatility and moderate cost.
In medium pressure mercury lamps a plasma that emits uv light is generated by applying electrical voltage.
A f ill material typically argon and precisely dosed amount of liquid mercury.
The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm.
These lamps also called mercury arc lamps are the workhorse of the light curing industry.
An electrode type medium pressure lamp consists of three major components.
The resulting photodegradation products were identified by 1 h nmr spectrometry.
Butyl methoxy dibenzoylmethane was irradiated for 100 h in a quartz immersion well photoreactor equipped with a medium pressure mercury vapor lamp.
They emit primarily in the blue and green.
Ultraviolet light can be divided into two ranges.
E lectrodes sealed into the end of the quartz sleeve.
Uv medium pressure mercury lamp electrode quadripin base helios produces ultraviolet lamps made of quartz glass with wavelengths from 185 to 400 nm.
Unlike most other uv sources the medium pressure lamp mpl has a polychromatic spectral distribution from 190 nm up to the infrared spectrum.
A quartz glass sleeve.
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.
The mercury medium pressure uv lamps are appreciated mainly for two applications.
Medium pressure mercury lamps produce characteristic bands at 313 and 365 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.
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.
Near uv spectral range 380 200 nm and far uv spectral range 200 10 nm.
Metal halide adding doping elements metal halide that change the spectrum of ultraviolet radiation thus optimizing it for different possible applications.
Analysis by gc ms showed that the total photodecomposition of butyl methoxy dibenzoylmethane had occurred.
Aquafine medium pressure mp lamp spectrum aquafine mp lamps are considered to be polychromatic lamps due to their wide output spectrum.
High pressure mercury vapor lamps are commonly used for general lighting purposes.
In medium pressure mercury vapor lamps the lines from 200 600 nm are present.
Mp lamps operate at roughly 800 c 900 c.
Thus within the scope of the physical possibilities wavelengths can be selectively generated.
Typical spectrum of a uv medium pressure lamp type hg for disinfection application the above spectrum is well suited for disinfection.
