Optimizing the Optical Power Output

The HL-2000-FHSA is adjusted at the factory to provide maximum power into a 200µm fiber. If a lower
optical power is required or a different fiber (bundle) diameter is used, you can adjust the optical power of
the unit. Refer to HL-2000-FSHA Diagrams
►
Procedure
Follow the steps below to adjust the optical power of the HL-2000-FHSA Light Source:
1. Connect a fiber optic spectrometer or an optical power meter to a fiber, and then connect the other
end of the fiber to the HL-2000-FHSA's SMA plug.
2. Loosen the blocking screw with the provided 1.3mm Allen wrench.
