Opto Engineering TCEDGEVIS Series

Telecentric system for defect detection on flat transparent materials


TCEDGEVIS telecentric optical systems provide a truly revolutionary approach to the inspection of flat transparent materials.

The special optical design ensures that only the light rays deflected by an object’s edge are imaged on the sensor: edges are automatically extracted without the need of software algorithms. This technique allows the detection of extremely tiny defects, particles and surface discontinuities that would be impossible to see with traditional lens systems. This approach is also suitable for OCR/OCV applications on clear glass, plastic films etc.

TCEDGEVIS telecentric optical systems include an EDGE telecentric lens, EDGE telecentric illuminator and mounting mechanics and are supplied as fully tested and pre-aligned optical benches.
