Details

Ocean Insight offers specular and diffuse reflectance standards for measurements of various types of sample surfaces. Reflectance measurements are a ratio of the reflected light spectrum to the incident light spectrum. Since there is no way to directly collect all of the light incident on a surface, reflectivity is usually measured relative to a reference standard. To ensure best results, the standard selected should be similar in reflectivity to the sample to be measured.

Overview

  • Diffusing materials – choose from PTFE or Spectralon standards
  • Specular reflectance standards -- aluminum mirror on fused silica substrate
  • High reflectivity over broad range – >95% reflectivity from 250-2200 nm
  • Additional options – other Spectralon reflectance standards and targets also available
