• Test and Correction of Distortion in Vision Systems
• Calibration of Perspective Error in Microscope Stages
• Measure Physical Field of View
Designed for calibration of vision systems and microscope stages, the Line Grid Target offers repeated parallel
lines in both X and Y axes. Using these lines as a reference, distortion and perspective error can be quantified
and calibrated out of a system. Two types of targets are available, Chrome on Glass, and Low Reflection
Chrome on clear glass, bonded to a white backing plate. The Low Reflection Chrome can be used with front
lighting, without creating highlights that degrade the image of the target.
