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 screw 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.
