ASBN-W High power Tungsten-Halogen Light Source Series article

ASBN-W High power TH light source series

  • Provides optimal illumination to monochromators
  • Offers excellent color temperature stability
  • Features adjustable constant voltage power supply
  • Contains focusable fused silica lens and UV protected Al coated mirror assembly
Optimum Illumination for Your Monochromator

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.
