ISP-REF Integrating Sphere

SELECT OPTION:

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.

ISP-REF-B Replacement bulb for ISP-REF.
