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 Spectralon disk for CC-3-UV-S and CC-3-DA correctors
- Spectralon material -- very high diffuse reflectance characteristics from 200-2500 nm
- Diffuser dimensions -- 3900 µm diameter (diffuser), 6.35 mm OD (cosine corrector assembly)
UV sterilization techniques can extend the life of high-demand personal protective equipment (PPE). But does your UV lamp provide enough power to disinfect face masks safely?
