Selecting a Wavelength
To select the desired wavelength:
Click the appropriate button in the Wavelength panel. A green light
identifies the selected wavelength.
To indicate a successful wavelength selection, the message Stabilization
in progress... appears on the data display (only if the source is an active
laser).
You can also select a wavelength from the QuickTools utility. For details,
see Monitoring Light Source Modules on page 29.
Note: The wavelengths specified in the Wavelength panel are the measured
wavelengths of the optical sources (to the nearest 1 nm for FP lasers, and
to the nearest 10 nm for LED sources).
