Full width at half maximum (FWHM)

Control of the output power
On the right of the screen, the percentage of the nominal output power of the SLED
can be adjusted from 0% to 100% with the following controls:
•
SLED ON/OFF button (2):
–
This button is OFF (grey) if the percentage is equal to 0%. By pressing it, it will
change to the ON state (light green) and the output power will be set to 100%.
–
This button is ON (light green) if the percentage is higher than 0%. By pressing it, it
will change to the OFF state (grey) and the output power will be set to 0%.
•
SLED Temperature (ºC)
•
SLED Current (mA)
•
Type of error (only when an error has
occurred, see Figure 5 on next page)
•
Keypad (3):
by clicking on the number, a keypad will
appear (Figure 3). A percentage 0%-100% can be
introduced by using it. You can erase a digit by pressing
‘DEL’. Press ‘OK’ to confirm the percentage. If the value
introduced is higher than 100%, it will be replaced by
the previous valid percentage.
•
Arrows (4):
using the up/down arrows will increase/decrease the current percentage
of the nominal output power by 1%.
•
Slide bar (5):
it permits you to adjust the output power from 0% to 100%. While
dragging the slide bar, it will be in yellow, and it will change to green once a value has
been selected.
On the bottom of the screen, if we click on “Spectrum view” (6), we will see the spectral
power distribution of the corresponding SLED (see Figure 4 on next page). The arrow (7)
