The Omnicon 3600 image analysis system offers feature and field specific measurements of area, width, thickness, etc., and can perform statistical and distribution analyses. The operator can select specific features for analysis or exclude them from evaluation. Data results and the images themselves can be saved on the hard or floppy disks. (Booths 1052, 1054, 1056) Artek Systems Corp.
