Product Details

ISP-R series fiber optic integrating spheres couple to Ocean Insight spectrometers to measure the total integrated reflectance of surfaces placed against the sphere’s sample port. ISP-R integrating spheres are well-suited for measurement of opaque or highly directional samples. The spheres are available in 6 mm and 8 mm sample port diameters and gloss-trap options are available that allow you to measure the specular component of the total integrated reflection.

Product Overview

  • Sphere material – PTFE
  • Wavelength range – 200-2500 nm (material)
  • Sample port diameter – 6 mm and 8 mm options (standard); up to 20 mm (custom)
  • Sphere diameter – 30 mm to 50 mm
