The AvaLight-DH-S is a powerful deuterium halogen source, but, like any unbalanced deuterium halogen source, it does have a very dominant alpha peak at 656 nm. This is why Avantes developed the DH-S-BAL, in which this peak is drastically reduced by a dichroic filter. This means less power, but an increase in the dynamic range of a factor 20. A comparison spectrum as taken with a standard AvaSpec-2048 is shown on the next page. The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet, visible and near-infrared range, from 200 to 2500 nm. An integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm are included. The TTL-shutter can be controlled from any AvaSpec spectrometer, which means the auto-save-dark option in AvaSoft software can be used (please note: IC-DB26-2 cable is needed). Connection to the fiber is done through an SMA-905 connector, which features an adjustable focusing lens assembly. This ensures you have the maximum possible power into your fiber. For all deuterium light sources, solarization resistant fibers (-SR) are recommended (see the fiber-optic section of this catalog). The output of the AvaLight-DH-S-BAL is optimized for fibers or bundles up to 1500 µm. Balanced light source Wide spectrum: 200-2500 nm Integrated TTL shutter High efficiency Increased dynamic range
