Cosine Correctors
Cosine correctors are optical diffusers (opaline glass, PTFE or Spectralon) that couple to fibers and spectrometers to collect signal from 180° field of view. Cosine correctors are specified for setups requiring the redistribution of incident light, such as measuring spectral irradiance of a plane surface in air or other media.
Typical applications include relative and absolute spectral intensity measurements of LEDs, light sources and other radiant sources (including solar). Options are available for connecting to optical fibers or spectrometers.
