ISP-R Integrating
Spheres for Reflectance
|
The ISP-R Integrating Spheres are distinguished by their compact size and sturdy design. Each has SMA 905 fiber ports at 90° (to connect to a spectrometer) and 8° (to connect to a light source for direct illumination). A gloss-trap version comes with two cylindrical pieces -- one is made of black absorbing material and the other of white reflecting material -- that fit into a hole at the top of the sphere for diffuse or specular reflection. |
Features
-
Fiber
Optic Spheres. Measure total integrated reflectance of
surfaces
-
Multiple Options. Choose from
spheres varying in sample port diameter (6-10 mm) and sphere diameter
-
Specular and Diffuse. Measure
specular and/or diffuse reflection with accessories or via integrated switch
The sphere is made of a sintered PTFE, which is >98% reflective in the visible. The spheres are available in diameters of 30 mm, 50 mm and 80 mm. Sample port diameters are 6 mm for the 30-mm sphere and 8 mm for the 50-mm and 80-mm spheres. (Call for custom port diameters.)
Each of the fiber optic integrating spheres described here couples to our spectrometers to measure the total integrated reflectance of surfaces placed against the sphere’s sample port. These integrating spheres are well-suited for measurement of variegated samples, as well as for analysis of opaque or highly directional samples. Gloss-trap options are available that allow you to measure specular or diffuse reflection.
Maximum Illumination Fiber Diameters
The maximum illumination fiber diameter that should be used with each
integrating sphere.
