AvaLight-DH-S-BAL Balanced Power
AvaLight-DH-S-BAL

The AvaLight-DH-S is a powerful deuterium
halogen source, but like any unbalanced
deuterium halogen source it does have avery dominant alpha peak at 656 nm. This
is why Avantes developed the DH-S-BAL, inwhich this peak is drastically reduced by adichroic filter. This means less power, but anincrease in the dynamic range of a factor 20.
A comparison spectrum, which is taken witha standard AvaSpec-ULS2048CL, is shown on
the next page.

Light Sources

The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet, visible and nearinfrared range, from 215 to 2500 nm. An
integrated TTL-shutter and filter holder for
filters of up to 50x50x5.0 mm are included.
The TTL-shutter can be controlled from any
AvaSpec spectrometer, which means theauto-save dark-option in AvaSoft software
can be used (please note: IC-DB26-2 cableneeded).

Connection to the fiber is done throughan SMA-905 connector, which features anadjustable focusing lens assembly. This
ensures you getting the maximum possible
power into your fiber. For all deuterium
light sources solarization resistant fibers arerecommended. The output of the AvaLightDH-S-BAL is optimized for fibers or bundles
up to 600 µm.
The filter holder can be easily replaced by adirect-attach cuvette holder CUV-DA-DHS(see section accessories) useful for fluorescence or absorbance measurements.
