TC EDGE VIS series

Telecentric system for defect detection on flat transparent materials

Catalog 2019

Overview

Tech info
Media gallery

TC EDGE VIS 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.

TC EDGE VIS 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.

KEY ADVANTAGES

  • Revolutionary method for inspecting flat transparent surfaces
    (clear glass, plastic films) and for OCR/OCV applications.
  • Extreme contrast
  • Even the smallest defects can be seen
  • Supplied as a ready-to-use optical bench

Notes

  1. Working distance: distance between the front end of the lens mechanics and the object.
    Set this distance within +/- 3% of the nominal value for maximum resolution and minimum distortion.
  2. Indicates the availability of an integrated camera phase adjustment feature.

Working principle: when light rays encounter an object they get scattered from its edges. The TCEDGEVIS optical system filters these rays to form an image of the object’s profile with much higher contrast than traditional optical methods
