The AvaLight-DH-S is a combined Deuterium and halogen light source, which can be used for UV/VIS/NIR applications. The AvaLight-DH-S has a SMA905 connector to be used with fiber optic cables and bundles. For optimal coupling an adjustable focus lens assembly is included. The light source supplies a continuous spectrum with high efficiency and highest stability in the UV, visible and near-infrared range from 215-2000 nm.
The Avalight-DH-S was developed based on the shine-through principle, in which the halogen light is focused through a small diameter aperture in the deuterium bulb.
For UV only applications the AvaLight-D-S source (only Deuterium) is available.
The standard AvaLight-D(H)-S light sources have a special UV longpass filter (>220nm) implemented to protect the fibers from solarizing. For applications that require a spectral range below 220 nm a Deep UV bulb is available, in which no UV longpass filter is included. For these Deep-UV measurements (from 190nm) the AvaLight-D(H)-S-DUV may be ordered.
For all Deuterium Light Sources solarization resistant fibers (-SR) are recommended, for the DUV lamp special solarization resistant fibers (-SR) are required (see the fiber optic section of our website).
