Cosine Corrector

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.

Replacement diffusers are available for the cosine corrector models with Spectralon or PTFE.

  • Cosine corrector accessory - replacement PTFE disk for CC-3-UV-T corrector
  • PTFE material - high diffuse reflectance characteristics from 200-750 nm
  • Diffuser dimensions - 3900 µm diameter (diffuser), 6.35 mm OD (cosine corrector assembly)
