5: Calibration
b. Set the Fiber diameter [um] (this is actually the diameter of the collection area, not just the
fiber) as follows:
For this type of collection area . . . Enter . . .
Bare fiber The fiber’s diameter in microns
CC-3 or CC-3-UV Cosine
Corrector 3900 microns as the effective diameter
CC-3-DA Cosine Corrector 7140 microns as the effective diameter
Any other collection area The collection area’s diameter as calculated in
microns
7. Place the collection area (bare fiber, CC3 etc.) at the distance specified by the lamp calibration
data. For example, if you are using the LS-1-CAL or DH-2000-CAL light source, the CC-3
Cosine Corrector is placed inside lamp opening. Bare fiber is fitted with a barrel first and then
inserted in lamp opening. If using an open calibration lamp like the Eppley or Oriel calibration
lamps, place bare fiber or the CC-3 tip at 50cm. If system sensitivity is low, you might need to
place the tip closer to lamp. Note that each distance has a matching lamp calibration file that you
must select in the application. Your choices are limited to distances that have lamp calibration
files, with first preference to place it at 50cm.
