DescriptionAvaLight-HAL Tungsten Halogen Light Source
From visible light to near infrared, that’s where the AvaLight-HAL works best. It’s a compact, stabilized halogen light source, with adjustable focusing of the fiber connection, maximizing output power at the desired wavelength. The light source also has adjustable output power to provide extra power or longer bulb life.
A filter-slot mounted on the front of the AvaLight-HAL accepts 1” round or 2” x 2” square filters, to block specific ranges of wavelengths or instantly lower the intensity. A direct-attached cuvette holder, CUV-DA-HAL, useful for fluorescence or absorbance measurements, replaces the filter holder and enables a fiberless illumination of cuvette cells.
The adjustable focus on the AvaLight-HAL helps you getting 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.
Optionally the ATT-DA-HAL can be ordered to attenuate the output from the AvaLight-HAL(-S), a combined direct-attach cuvette holder and attenuator is available as well (CUV-ATT-DA-HAL).
The optical output can be controlled through an internal jumper. At low setting the lamp has a color temperature of 2700K but provides over 4000 hours of lifetime. The standard or medium setting changes the color temperature to 2850K and provides 50% more power with a bulb lifetime of 2000 hours. The high power setting gives a color temperature of 3000K, doubles power compared to the long-life setting and gives you up to 1000 hours of lifetime.
The AvaLight-HAL-S features an internal TTL-shutter, controllable from your AvaSpec spectrometer. This gives you the ability to use the auto-save dark option in AvaSoft spectroscopy software.
For more demanding environments we developed the AvaLight-HAL-S-IND, that comes with a heavy-duty industrial power connector and 24V power adapter included. This connector is also available as an upgrade to your existing AvaLight-HAL-S.
