Imaging Sphere – Scatter and Appearance (IS-SA)

High speed, low cost, scatter and appearance measurementsystem for metal, paper, plastics and transmissive films

The Scatter & Appearance Imaging Sphere (IS-SA) utilizes scattered light measurement to accurately and rapidly characterize surface roughness, imperfections and diffusion properties in a wide range of reflective surfaces and transmissive films. System software then automatically converts raw scatter measurements into commonly used surface parameters such as TIS (Total Integrated Scatter), RA (average surface roughness), BRDF and BTDF. Based on patented technology developed jointly with Royal Philips Electronics, the IS-SA acquires data over an entire 2 steradians in a single measurement, taking just seconds, which is a dramatic improvement over traditional scatter instruments. The turnkey IS-SA system consists of a 20" (508 mm) diameter, hemispherical measurement dome, mated with our PM-1403F-1 Imaging Colorimeter (with a 512x512 CCD pixel detector). The IS-SA is equipped with a variable angle, collimated illumination system. The IS-SA includes a full software suite, which enables manual and fully automated control of all system hardware, as well as complete data analysis and display. Data can be displayed as isometric plots, cross-sectional graphs, radar plots, bit maps and color graphs.
