Product Details

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.

The 74-90-UV-CC3 is a specialty sampling optic that requires an additional 74-UV collimating lens to complete an assembly that will connect to your fiber. We recommend consulting an Ocean Insight Application Engineer to ensure best results. 

Product Overview

  • Wide FOV – collects light from 180° field of view
  • Specialty sampling device – combination of right angle reflector and cosine corrector
  • Special configuration -- requires additional 74-UV collimating lens to connect to optical fibers

In the battle against COVID-19, 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?
