The ASBN-W high power tungsten-halogen series are complete light source assemblies with 50W/75W/100W/150W tungsten-halogen lamps that emit in the 300 to 2600 nanometer (nm) wavelength region. They have been designed to transfer the maximum possible illumination from a tungsten-halogen lamp to Digikröm monochromators. The tungsten-halogen lamps of the ASBN-W high power series are near blackbody sources of light with fused silica envelopes around the lamp filaments. The housing contains a 1" UV grade fused silica lens (f#/1.2) and UV protected Al coated mirror (f = 12.5mm) assembly selected for optimum coupling to the monochromator or the fiber, a regulated power supply and a cooling fan. The power supply provided with the ASBN-W high power series is a DC voltage regulated power supply.

• Spectrum

The Tungsten-halogen light source is a well known near black body radiation source.  Its spectrum is also very similar with those of black body radiation.

The envelope of tungsten-halogen lamps is made of quart.  Quartz transmittance, therefore, needs to be considered.
