AvaLight-HAL, 10W Tungsten Halogen Light Source
The AvaLight-HAL is a compact stabilised halogen fan-cooled light source that can be used for the visible range and the near infrared.
The AvaLight-HAL features adjustable focusing of the SMA connector to maximise light coupling into a fibre or fibre bundles with a diameter of up to 600µm. A filter slot accepts 1" round or 2" x 2" square filters up to 3mm thick. The lamp stability is achieved by a current stabilisation. A fan regulates the airflow around the heatsink to optimise the operation temperature.
The AvaLight-HAL requires a PS-24V/1.25A 24 VDC power supply unit for operation.
The SMA connector input into any fibre can be optimised by changing the focus. Bulb replacement is easy. With an internal jumper the optical output energy can also be controlled. In the 'low' setting, the source acts as a long life source with over 2000 hrs life time. In the 'medium' setting, the colour temperature increases and the expected life time is around 1000 hrs. The 'high' setting has a the maximum output in the blue range, but bulb lifetime is reduced to >1000 hrs (see curve illustration at the top of the page).
The AvaLight-HAL-S has an internal TTL shutter, that can be controlled from the AvaSpec, so the auto-save dark option in the AvaSoft software can be used (an IC-DB15-2 or IC-DB26-2 is required).
The filter holder can be easily replaced by a direct attach cuvette holder CUV-HAL (see accessories section) which is especially useful for fluorescence or absorbance measurements.
As an option, the AvaLight-HAL(S) can be delivered in a rackmounted version, to be fully integrated in 9" rackmount or 9.5" desktop housing.
