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 ...

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 ...

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 ...

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 ...

Perspective errors, or parallax, are part of everyday human experience. In fact, they let the brain interpret the 3D world. For example, closer objects to appear relatively larger than those away.

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 ...

Key Companies Covered in the Telecentric Lenses Research are Navitar Optical Solutions, Seiwa Optical, Lensation GmbH, Jenoptik, Keyence, ULO Optics, Thorlabs, MYUTRON, Edmund Optics, Optart ...

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 ...
