Fiber Diameter – If the light source is not inside the integrating sphere, you must enable

this option and enter a value in the field (in microns) equivalent to the diameter of the
opening of the integrating sphere that is capturing the measured light. There are 25,400
microns per inch. For example, for the FOIS-1, the value would be 9525 microns (equals
3/8 of an inch).

 However, if a light source is inserted into the sphere, this value is ignored. If a cosine

corrector is used, define the light collection area as follows:

If this cosine corrector is used . . .

Enter this diameter (in um) . . .

SpectraSuite then calculates the collection area from the fiber diameter.

Calibration

You can calibrate your spectrometer in two ways:

 Ocean Optics can calibrate the spectrometer for you and send you the resulting

calibration file, or

 You can calibrate the spectrometer yourself using a light source (calibration lamp) with

known spectral output (microwatts per square centimeter per nanometer) using this menu
item.

Combine Calibration Files

This feature allows you to combine two spectrometer calibration files that you have created; one file
using a calibrated deuterium lamp source (UV) and the other using a calibrated tungsten lamp source
(VIS). This will result in a spectrometer calibration file that can be used across the entire spectral range.
