Adjustment of focusing in SMA fiber
The AvaLight is factory adjusted to optimally focus the output into a 200µm fiber. If lower optical
power is recommended or a different fiber (bundle) diameter is used, the optical power can be
adjusted.
9.
Connect your fiber optic spectrometer or your optical power meter to a fiber to the Fiber input
10.
Loosen blocking-screw with delivered Allen key (1,3mm).
11.
By shifting the SMA socket you can optimize your optical power.
12.
Secure position by tightening the blocking screw .
