12. Select the correct diameter of your probe from the following:
 If you are using an integrating sphere, select the Use Integrating Sphere option.
 If you are using a bare fiber or a cosine corrector, select Fiber Diameter and enter the
appropriate value. See the following examples:
Cosine Corrector Fiber Diameter Area in cm 2
CC-3 3900 microns 0.119459061
CC-3-UV 3900 microns 0.119459061
CC-3-DA 7140 microns 0.400392842
QP600-2-VIS/BX fiber 600 microns 0.002826
 If you know the collection area, select Collection Area and enter the value. Remember the
area in cm
2 to enter it in the config.txt file on the SD Card. If you enter the diameter in
micrometers, the software will calculate the area in cm
2
automatically.
13. Click Finish. If you unblock the calibration light source, you will be able to view the calibrated
output power of the light source in absolute irradiance units (uWatt/ cm 2 /nm).
