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 ...

• 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 ...

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 ...

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 ...
