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 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.
A spare bulb (ISP-REF-B) is available for the sphere lamp. The bulb has 900-hour lifetime and 3100 K color temperature.
