The Cobra 3-D laser scanner uses computer-controlled motion to scan surfaces in a succession of linear profiles. From Optical Gaging Products Inc., this device includes Scan-X data analysis software, which displays the profiles and allows direct readout of dimensional relationships. Surfer mapping software that provides color maps of the area topography also is available. The Cobra scans areas as large as 5000 sq mm using standard models. It also accommodates surface height changes up to 8 mm and offers a Z-axis resolution as fine as 0.125 µm.
