CC-3 Series Cosine-corrected
Irradiance Probes
Instructions
Overview
The CC-3 Cosine-corrected Irradiance Probes are spectroradiometric sampling optics designed to
collect radiation (light) from approximately a 180° field of view, thus eliminating light collection
interface problems inherent to other sampling devices.
The following models are available:
• CC-3 – Has Opaline glass-diffusing for a wavelength range of 350 – 1000 nm
• CC-3-UV-S – Has Spectralon
TM material for a wavelength of 200–2500 nm
• CC-3-UV-T – Has PTFE material for a wavelength of 200 –750 nm
• CC-3-DA – Has Spectralon material for a wavelength of 200–2500 nm
Operation
The CC-3-UV-T Cosine Corrector’s Teflon TM diffusing material is a thin disk that sits at the end of the
barrel (the Teflon material is 0.30" thick), while the CC-3-UV-S and CC-3-DA (Spectralon diffuser)
have a much thinner material (0.007” thick) which is substantially more dense than the Teflon. Both
cosine corrector types have a 0.25" OD barrel with a smooth yet rugged black oxide finish. Both the
CC-3 and the CC-3-UV models are screwed onto the end of an optical fiber, making an irradiance
probe. The probe couples to a spectrometer to measure the intensity of light normal to the probe
surface. When coupled to a spectrometer, these irradiance probes can be used to measure UV-A and
UV-B solar radiation, environmental light fields, lamps and other emission sources.
