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

TM

• CC-3-UV-S – Has Spectralon

• 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

material for a wavelength of 200–2500 nm

Operation

The CC-3-UV-T Cosine Corrector’s TeflonTM 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 measu re 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.

CC-3 Series Cosine Correctors Instructions

The CC-3-DA screws directly onto the SMA 905 connector of a spectrometer, creating a complete
spectroradiometric system and eliminating the need for an optical fiber.
