Avantes Deuterium light sources are known for their stable output ad are used for UV absorption or reflection measurements. These can also be used as irradiance calibration sources due to their high stability. The standard AvaLight-DH-S mixes the halogen light with the Deuterium light, thus producing a wide spectral range light source. The output spectrum of Deuterium light sources exhibits several peaks, with a prominent peak at 656 nm. The AvaLight-DH-S-BAL incorporates a dichroic beam splitter installed to minimize these peaks, providing a smooth spectrum from 200-2500 nm.
From visible light to near-infrared, that’s where the AvaLight-HAL-S-Mini works best. The AvaLight-HAL-S-Mini is a compact, stabilized halogen light source with adjustable focusing of the fiber connection, maximizing output power at the desired wavelength. Besides that, this versatile light source also has an adjustable electrical power output to provide extra power or longer bulb life.
A filter slot mounted on the front of the AvaLight-HAL-S-Mini accepts 1″ round or 2″x2″ square filters, to block specific ranges of wavelengths or instantly lower the intensity.
The adjustable focus on the AvaLight-HAL-S-Mini helps you get the most out of your light source: it makes sure all possible power is transmitted through your optical fiber. Bulb replacement is easy and can be done in a matter of minutes.
A combined direct-attach cuvette holder and the attenuator is optionally available (CUV-ATT-DA-HAL). For attenuation, you can use the in-line filter holder (FH-INLINE) or the in-line attenuator (ATT-INL).
The optical output can be controlled through a dongle at the backside or from your spectrometer. At the lowest setting, the light bulb has a color temperature of 2647K, but provides a significantly longer lifetime. The standard or medium setting changes the color temperature to 2759K and provides around 30% more power with a bulb lifetime of 2000 hours. The high-power setting gives a color temperature of 2879K, about 70% more power compared to the long-life setting with a reduced lifetime of the bulb.
The AvaLight-HAL-S-Mini features an internal TTL shutter, controllable from your AvaSpec spectrometer. This gives you the ability to use the automatic save dark option in our AvaSoft spectroscopy software.

In need of more power than the AvaLight-DHc? The AvaLight-DH-S is Avantes’ most powerful deuterium halogen source. Like the DHc, the DH-S is also a combined deuterium and halogen light source, capable of transmitting light in the UV/VIS/NIR-range, but has 35 times more halogen output and up to 300 times more deuterium power. The source has a prominent 656 nm deuterium peak which can limit dynamic range (see Avalight-DH-S-BAL as an alternative). It includes a focusing lens assembly, to fully utilize the possibilities and size of your fibre.
The AvaLight-D-S is a deuterium light source only, making it a great option for measurements in the UV range, 190 to 400 nm. The AvaLight-D-S-DUV version starts even lower at 175 nm, for your deep-UV experiments. This version also offers twice the intensity at 200 nm.
The output of the AvaLight-DH-S is optimized for fibres or bundles up to 600 micrometres. For larger fibres, the focal point is manually adjustable to optimize the light coupling into your fibre.
The AvaLight-D(H)-S features an integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm.

Get the best of two worlds with the AvaLight-DHc. It has both a deuterium light source and a halogen light source, providing you with adequate light between 200 and 2500 nm for nearly all absorbance chemistry applications. Deuterium emits light between 200 and 550 nm, whereas halogen emits light of up to 2500 nm. Coupling to the rest of your spectroscopy system is easy with the SMA connector.
This light source is recommended in settings with large fibre cables or direct-attachment to a cuvette holder such as the CUV-DA, due to its relatively low output energy. The integrated TTL-shutter makes saving a dark measurement very simple in combination with AvaSoft (extra IC-DB26-2 needed).
The AvaLight-DHc is optionally available in a rack-mountable version, to be used in the 19” rack or the 9.5” desktop system.
A direct-attach cuvette holder CUV-DA is available for fluorescence or absorbance measurements.

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.
The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet, visible and near-infrared range, from 215 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 fibre is done through an SMA-905 connector, which features an adjustable focusing lens assembly. This ensures you have the maximum possible power into your fibre. For all deuterium light sources, solarization-resistant fibres (-SR) are recommended (see the fibre-optic section of this catalogue). The output of the AvaLight-DH-S-BAL is optimized for fibres or bundles up to 1500 µm.
The filter holder can be easily replaced by a direct-attach cuvette holder CUV-DA-DHS (see section accessories) useful for fluorescence or absorbance measurements.
