(CC-3-DA) Direct-Attach Cosine Corrector with Spectralon Diffuser

Ocean OpticsSKU: CC-3-DA


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.

Wide FOV – collects light from 180° field of view

Versatile – 74-DA version couples directly to the spectrometer

Applications — ideal for intensity measurements of LEDs, light sources and solar sources
