ASBN-W HighPower Light Source

Optimum Illumination for Your Monochromator


- Provides optimal illumination to monochromators

- Offers excellent color temperature stability

- Features adjustable constant voltage power supply

- Contains focusable fused silica lens and UV protected Aluminum coated mirror assembly


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. Please click here to view the manual for this light source.
