Tungsten Halogen Lamp Wavelength Range

Instruments that only use tungsten halogen lamps as the light source will only measure in the visible region.

Tungsten halogen lamp wavelength range.

The deuterium lamp has a short emission wavelength of 400 nm or less. 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. 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 window material limits its use at the short wavelength end.

For a significant portion of the visible wavelength range the color temperature of. Also known as tungsten or quartz lamp and the wavelength range of halogen lamp is in the visible light region which is in the range of 320nm to 1100 nm. A deuterium lamp requires a large and complex power supply making it more expensive than a halogen lamp. Wavelength range although as mentioned before our halogen lamps supply ranges from 10 100 w but 315 380 nm is the wavelength range.

Tungsten halogen also known as quartz iodine lamps these measure most effectively in the visible region from 320 1100 nm. The correction function was determined by measuring the. 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 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.

General halogen lamp life is about 2000 hours or more. If the instrument is equipped with a halogen lamp only it means the instrument can only measure visible light. 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 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. However it is one of the few continuous spectrum light sources that is stable in the ultraviolet range.
