Product information "AvaLight-DH-S-BAL Deuterium-Halogen Light Source"
Balanced Power; 200-2500 nm; Drift <±0.1, <±0.5%/h; Optical Power 6-448 µW; Halogen Lamp Colour Temperature 3,000 K; Power Supply 100-240 VAC, 50/60 Hz
Avantes’ AvaLight-DH-S is a powerful light 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.
The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet (UV), visible (VIS) and near-infrared (NIR) 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 filter holder can be easily replaced by a direct-attach cuvette holder CUV-DA-DHS, useful for fluorescence or absorbance measurements.
The TTL-shutter can be controlled from any AvaSpec spectrometer, which means the auto-save-dark option in AvaSoft software can be used. 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. The output of the AvaLight-DH-S-BAL is optimized for fibers or bundles up to 1500 µm.
