Square Continuous Diffuse Illuminators
SCDI
The SCDI provides extraordinary diffuse illumination performance. The
patented design of the SCDI makes it ideal for moderately faceted and
undulating specular surfaces. The SCDI is designed for those critical
applications involving highly specular surfaces where any reflections of
camera aperture or "seams" in the lighting envelope will cause a vision
system to see defects where none exist. Examples of such applications
include compact disk artwork verification and the inspection of solder
patterns on circuit boards. The SCDI allows products to be inspected "in the
package"--even blister-packaged pharmaceutical products and computer chips
in the tube. The SCDI is designed for imaging applications requiring
significantly greater uniformity of diffuse illumination than provided by
the DOAL.
