Availability:

ISP-R series fiber optic integrating spheres couple to Ocean Optics 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.

  • Versatile – adaptable for diffuse or specular measurements
  • High reflectivity – PTFE sphere coating is >98% reflective from 400-1500 nm
  • Multiple options – available with sample port diameters of 6 mm and 8 mm
