Settings for high power, long life or disable
The AvaLight-HAL-MINI factory settings are for normal power output. The optical energy can be
changed to Long-Life or High-Power modes by setting the correct I/O pin to High-level on the
external I/O connector.
With the disable function that is present on the I/O connector the user can disable the optical
output of the light source by setting this signal to high-level.
When the light source is used in combination with an AvaSpec spectrometer, interface cable IC-
DB26-2 and AvaSoft, the optical output can be changed by AvaSoft. It is also possible to disable and
enable the light source by AvaSoft. See appendix A.
When the light source is not connected with an interface cable, the DONGLE-MINI-H for high power
or the DONGLE-MINI-L for long life can be placed on the I/O connector to change the optical output.
See appendix B.

Adjustment of focusing in SMA fiber
The AvaLight-HAL-MINI factory settings are adjusted to the optimal focus of the output into a 200µm
fiber. If a different optical power is needed or a different fiber (bundle) diameter is used, the
focusing of the light source on the fiber can be adjusted as described below.
1.
Connect your fiber optic spectrometer (or your optical power meter) to a fiber onto the
AvaLight-HAL-MINI SMA connector.
2.
Unscrew locking-screw, of the collimating lens, with delivered Allen key (1.3mm).
3.
By shifting the SMA socket optical power can be optimized.
4.
Secure position by tightening the locking screw.
