Optical Diffusers Collect Light from 180° FOV
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.
- Wide FOV – collects light from 180° field of view
- Versatile – couples to fibers or directly to spectrometers
- Irradiance-ready – ideal for intensity measurements of LEDs, light sources and solar sources

* In spectroradiometrically calibrated setups, the CC-3-DA must remain attached to the spectrometer to maintain calibration. Removal of the CC-3-DA to replace the diffuser would require recalibration of the setup.
