The AvaLight-HAL is a compact stabilized 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 maximize light coupling into a fiber or fiber bundle with a diameter of up to 600 µm. A filter slot accepts 1" round or 2" x 2" square filters up to 3 mm thick. The lamp stability is achieved by a current stabilization. A fan regulates the airflow around the heatsink to optimize the operation temperature. The AvaLight-HAL needs an extra PS-24V/1.25A 24 VDC power adapter.
The SMA-connector input into any fiber can be optimized by changing the focus. Bulb replacement is easy. With an internal jumper the optical output energy can be controlled. At "low" setting the source acts as a long life source with over 2000 hrs life time. At "medium" setting the color temperature goes up and the expected life time is about 1000 hrs. The "high" setting gives max output in the blue range, but reduces bulb life time to > 1000 hrs (see fig 9).
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 (extra IC-DB15-2 or IC-DB26-2 needed).
The filter holder can be easily replaced by a direct attach cuvette holder CUV-HAL (see section accessories) useful for fluorescence or absorbance measurements.
Optionally, the AvaLight-HAL(S) can be delivered in Rackmounted version, to be fully integrated in the 19" rackmount or 9.5" desktop housing.
