The FD-D8R is a robust, non-contact, real-time spectrophotometer designed for use in industrial applications. Its novel, compact design allows measurement of color with the specular component included or excluded using diffuse illumination and an 8° measurement angle, without the need to be tethered to optical fibers.

At the core of the FD-D8R is the integration of illumination optics and measurement sensors into a compact assembly. It has a fully sealed, chemically resistant case with a cleanable/replaceable sapphire window, which protects the integrating sphere and internal optics from contaminants. Reflectance is measured in the visible range of 400-700 nm and provides CIE color coordinates for your choice of illuminant.


  • Reflective color measurements -- diffuse/8° measurement geometry, specular included or excluded

  • Outputs -- reflectance and CIE colorimetric data from 400-700 nm

  • Non-contact measurements -- ideal for delicate parts in challenging industrial environments

  • Industrial design -- sealed measurement head protects sampling optics; real-time measurements ensure accuracy and reliability
