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 ...

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 ...

Telecentric lens have constant magnification when changing in objective distance. There is no perspective error when viewing 3D object. It is widely used in machine ...

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 ...

Boasting the largest field-of-view of all of Edmund’s MVO telecentric lenses, this 0.08T lens delivers a 4-in. horizontal field-of-view when connected to a 2/3-in. CCD. Working distance ranges from ...

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 ...

The microscope combines a big telecentric photolithography lens with a large tube lens to create sharp, detailed images of large and curved samples. These lenses project the image onto a flat array of ...
