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 ...

• 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 ...

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 fact, they let the brain interpret the 3D world. For example, closer objects to appear relatively larger than those away. This phenomenon is also present in imaging systems in which the size of an ...

This work required the development of a telecentric lens plug-in for DIRSIG. This plug-in would closely mimic DIRSIG's OrothImage plug-in, however, still allow for depth of focus effects as seen from ...

Telecentric Lenses are widely used in metrology instruments, laser marking systems, and AOI (Automatic Optical Inspection) machines. Here’s a 360 view of one of our custom Telecentric Lenses which was ...

Barrington, NJ. Edmund Optics is now offering its TECHSPEC compact telecentric lenses with six new models with working distances of 220 mm and 300 mm. Featuring a telecentric design across all ...
