Fit a lens f 50 mm in the tilting rider and set it up about 10 cm from the lamp.
High pressure mercury lamp wavelength.
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.
Mercury hg arc lamps are ideal light sources for applications that require high intensity spectral lines emitted in the deep uv to visible light regions.
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.
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.
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.
Two varieties of such lamps exist.
Set up the high pressure mercury lamp roughly in the mid dle of the 1 m optical bench.
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.
Medium pressure mercury arc ushio produces standard and custom uv emitters.
Place the adjustable slit another 10 cm or so beyond it in such a way that the slit is well illuminated.
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.
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.
New high power amalgam lamps are significantly more powerful than low pressure lamps.
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.
It may be necessary to incline the tilting rider a little.
Medium pressure lamps produce the greatest uv output per unit length of lamp of the 3 lamp types.
These lamps have a much broader spectral distribution that includes germicidal wavelengths.
Low pressure mercury lamps fluorescent tubes and high pressure mercury lamps are also used for disinfection and sterilisation.
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.
A typical hg high pressure discharge lamp with a power of 400 w has a wall plug efficiency of 20 i e.
