The ISP-REF Integrating Sphere provides even surface illumination for reflectance measurements of surfaces such as the color of flat samples.
The ISP-REF has 10.32 mm (0.41”) sample port aperture, a transfer optic assembly for restricting the fiber viewing angle and a built-in tungsten-halogen light source. The sphere is coated with Spectralon®, a white diffusing material that provides a highly Lambertian reflecting surface. A simple switch allows users to manipulate the sphere for the inclusion (I) or exclusion (E) of specular reflectance.
- Versatile – adjusts for diffuse or diffuse plus specular measurements
- High reflectivity – Spectralon coating is >98% reflective from 400-1500 nm
- Built-in light source – provides even surface illumination for reflectance
