Medium Pressure Uv Lamp Wavelength

In such a spectrum there are separate discrete points of increased intensity so called spectral.

Medium pressure uv lamp wavelength.

The uv lamp never contacts the water. The low pressure uv lamp is only capable of producing lines at 185nm and 254 nm. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around 250 nm. Medium pressure mercury arc ushio produces standard and custom uv emitters.

This photolysis process has a lot of application in pools reduction of combined chlorine and process water de chlorination de ozonation toc reduction. Uvc maintenance over the life of the lamp is much higher over the life of the lamps. In medium pressure mercury vapor lamps the lines from 200 600 nm are present. The medium pressure lamp emits its radiant energy between 250 and 350 with many energy spikes in between most notably around 320 which is more in the uvb range with a uvc efficiency around 7 15.

Fused silica is used in the manufacturing to keep the 184 nm light from being absorbed. Wavelength nm spectrum uv medium pressure lamp gallium doped relative spectral intensity distribution nm uv medium pressure lamps emit a so called discontinuous spectrum or line spectrum graphic 4 during operation. The distribution of energy over the wavelength ranges is depicted on the left. The uv lamps for water treatment consist of specialized low pressure mercury vapor lamps that produce ultraviolet radiation at 254 nm or medium pressure uv lamps that produce a polychromatic output from 200 nm to visible and infrared energy.

The emission peak of the mercury electron transition within these low pressure hot cathode uv lamps is fixed in both energy and wavelength. Unlike most other uv sources the medium pressure lamp mpl has a polychromatic spectral distribution from 190 nm up to the infrared spectrum. Quartz germicidal uvc lamps can produce both 254nm wavelength killing wave and 185nm wavelength ozone. Medium pressure uv lamps have a multispectrum wavelength for this reason smp unit has the ability to break chemical bonds and have a good reduction of unwanted chemicals in water.

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. Roughly 35 of the electrical energy imparted into the lamp becomes uv c energy of the 254nm wavelength.
