Spectralon is an example of a reference standard to take a white reference
against. (Labsphere, Inc., Shaker St., PO Box 70, North Sutton, NH
03260-0070, PH: 603-927-4266, FX: 603-927-4694, E-mail:
sales@labsphere.com, Website: www.labsphere.com). Spectralon is also
available from ASD.
Take a White Reference (or baseline reference).
Observe samples.
Follow the instructions for plugging in the instrument and starting the Indico
software.
Attach any required foreoptic accessories.
Open a new project either by selecting File->New Project from the
pull-down menu.
Type in a name for this project and click on the OK button.
Select Spectrum->Sample Count/Average from the pull-down menu.
Set the Instrument Sample Count to 100 for outdoor solar illumination
and click OK.
Note: The actual spectrum average will be determined by striking a
compromise between noise reduction through averaging the spectra
and the time desired for each spectrum collection. For instance, if you
are using the instrument in the field, are walking a large area, and are
making frequent spectral readings, you will want a shorter average
setting than if you are collecting spectra in-situ and desire the cleanest
spectra possible.
The project screen will return, and the sample count will be displayed in the
status box at the bottom of the graph.
Make sure the light source is on and the probe input end is pointed at the
white reference panel.
Select Spectrum->Take a Baseline [Alt+S, B] [Ctrl+R]. When
prompted, click Yes, take a new white reference.
• The FieldSpec spectroradiometer optimizes the detector sensitivities for
the probe and light source currently being used.
• The dark offset and white reference will also be measured and saved.
• Status bars will indicate each process.
When optimization and white reference are complete, you should see a
straight baseline across the Project Graph at 1.00 (100%).
Select the Display->Reflectance [Alt+D, R] for the reflectance mode.
