Dimension Measurement System

Description

The IM Series image dimension measurement system combines the speed and flexibility of a vision system with the accuracy of a double telecentric lens, making it possible to obtain high-accuracy, reliable measurements in a minimum amount of time.

Simply place a target on the stage and press the button. Up to 99 points are measured in a matter of seconds with a repeatability of 0.5 micron. The Intelligent Pattern Analysis Search System (iPASS) determines the position and orientation of targets and compares their shapes against those of recorded targets.

The large 100 mm dual telecentric lens captures entire targets in a single image for simultaneous measurement of all points. This technology allows pixels to be captured as if the lens were vertically positioned.

As a result, measurements are not affected by distortions or distance. In addition, measurement data can be saved and exported as reports or to statistical packages. Anything can be measured, from inside diameters, circular pitches and angles to the most complex dimensions.

Another way the IM-6000 Series enables stable edge detection is by ignoring abnormal edge points, even in situations where a target has burrs or chips that lead to errors during the least- squares adjustment.

With an accuracy of one-hundredth of a pixel, Keyence’s proprietary sub-pixel processing system detects edge positions more accurately than conventional systems. When edges are extracted manually with the naked eye, discrepancies between operators are virtually impossible to avoid.

Furthermore, the system measures dimensions without moving the XY stage, thus eliminating vibration-induced errors.
