Cosine Function
5.5.2 Cosine corrector
The cosine correctors are spectro radiometric sampling optics, designed to collect radiation (light)
over 180°, thus eliminating optical interface problems associated with the light collection sampling
geometry inherent to other sampling devices.
The CC-UV/VIS cosine corrector has teflon diffusing material and is optimized for applications from
200-1100 nm. For the VIS/NIR range (350-2500nm) a Radin material is available in the CC-VIS/NIR.
Both cosine correctors screws onto the end of any SMA-terminated optical fiber. When coupled to a
miniature fiber optic spectrometer, these cosine correctors can be used to measure UV-A and UV-B
solar radiation, environmental light, lamps and other emission sources.
The Cosine Correctors have a 0.25" O.D. barrel with a smooth yet rugged black oxyde finish. The
diffusing material is a thin disk that fits at the end of the barrel. The cosine corrector has an SMA
905 connector for convenient coupling to optical fibers.
