A telecentric lens has the unique property of maintaining a constant magnification over a specific range of object distances. This property lets inspection systems make accurate dimensional ...

Finding the right set of lenses for your machine vision system can be a daunting task. Wiebke Marzahn of Sill Optics addresses some common concerns by breaking the puzzle down into a number of key ...

Edmund Optics® (EO), the premier provider of optical components, introduces its TECHSPEC® In-Line Compact Telecentric Lenses. These versatile lenses feature an ultra-compact design with a small ...

My July column (“Calibrate camera coordinates and colors”) described techniques you can use to calibrate vision systems. In some cases, though, basic calibrations do not suffice. General-purpose ...

• In a telecentric lens, the rays which pass through the center of the aperture are parallel to the optical axis in front of or behind the system. •Backlighting via telecentric lenses can eliminate ...

For many industries and applications, implementing inspection at the point of assembly improves quality of the supply chain while reducing the impact of downstream detection of defects. Eliminating ...
