Tungsten Halogen Lamp Wavelength Range

A halogen lamp also known as a tungsten halogen quartz halogen or quartz iodine lamp is an incandescent lamp consisting of a tungsten filament sealed into a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen such as iodine or bromine the combination of the halogen gas and the tungsten filament produces a halogen cycle chemical reaction.

Tungsten halogen lamp wavelength range.

If the instrument is equipped with a halogen lamp only it means the instrument can only measure visible light. A deuterium lamp requires a large and complex power supply making it more expensive than a halogen lamp. The window material limits its use at the short wavelength end. Tungsten halogen lamps are ideal light sources for spectrophotometers as they provide broadband spectral radiation ranging from the ultraviolet through the visible and into the infrared out to five microns.

Wavelength range although as mentioned before our halogen lamps supply ranges from 10 100 w but 315 380 nm is the wavelength range. However it is one of the few continuous spectrum light sources that is stable in the ultraviolet range. We have developed a physical model for the spectral irradiance of 1 kw tungsten halogen incandescent lamps for the wavelength range 340 850 nm. The correction function was determined by measuring the.

Using press to read technology the lamp life of tungsten halogen lamps can be extended to approximately 3000 hours. Non uv blocked quartz envelope some of the commercial tungsten halogen lamps come with uv blocked quartz that results which is unsuitable for getting accurate results. Tungsten halogen lamps from heraeus noblelight for the visible wavelength range of your hplc detector the following search form enables you to specify the original manufacturer and oem number in order to find suitable replacement parts from third party manufacturers. The model consists of the planck s radiation law published values for the emissivity of tungsten and a residual spectral correction function taking into account unknown factors of the lamp.

The deuterium lamp has a short emission wavelength of 400 nm or less. Tungsten halogen also known as quartz iodine lamps these measure most effectively in the visible region from 320 1100 nm. Lamp seal temperatures must not exceed 350 c or oxidation of the molybdenum ribbon will occur resulting in premature lamp failure. We have developed a physical model for the spectral irradiance of 1 kw tungsten halogen incandescent lamps for the wavelength range 340 850 nm.

For a significant portion of the visible wavelength range the color temperature of. Tungsten halogen lamps the most advanced design in this class generate a continuous distribution of light across the visible spectrum although most of the energy emitted by these lamps is dissipated as heat in the infrared wavelengths see figure 1.
