High Pressure Mercury Lamp Wavelength

High and low pressure uv mercury vapour lamps heraeus manufactures low and high pressure mercury vapour lamps used for applications such as photochemical processing fluorimetry mercury analysers medical and environmental equipment and fixed wavelength detectors.

High pressure mercury lamp wavelength.

Two varieties of such lamps exist. The uv fraction 250 380 nm is about 30 but depending on. Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. Set up the high pressure mercury lamp roughly in the mid dle of the 1 m optical bench.

Medium pressure lamps produce the greatest uv output per unit length of lamp of the 3 lamp types. A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Their unique uv emission spectra make them popular for unique applications that need enhanced uv output such as uv spectroscopy uv curing and other industrial processes and environmental. As the main arc strikes and the gas heats up and increases in pressure the light shifts into the visible range and the high gas pressure causes.

In total 80 w optical power. It may be necessary to incline the tilting rider a little. Low pressure mercury lamps emit an almost monochromatic light with a wavelength of 253 7nm. These lamps have a much broader spectral distribution that includes germicidal wavelengths.

Place the adjustable slit another 10 cm or so beyond it in such a way that the slit is well illuminated. 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. Fit a lens f 50 mm in the tilting rider and set it up about 10 cm from the lamp. Even though more cleaning may be required for medium and amalgam lamp based systems because they have a smaller number of lamps in the uv unit these systems can.

New high power amalgam lamps are significantly more powerful than low pressure lamps. 1906 higher pressure mercury vapor light in a fuzed quartz tube is developed kuch retschinsky siemens munich 1936 the modern high pressure mercury vapor lamp is developed type mb philips nederlands no individual names are available. When a mercury vapor lamp is first turned on it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low so much of the light is produced in the ultraviolet mercury bands. Low pressure mercury lamps fluorescent tubes and high pressure mercury lamps are also used for disinfection and sterilisation.
