The zebra mask ZB from EFFILUX is the ideal mask for metrology and deflectometry to reveal defects (stripe, impact, or positioning, etc) on reflective / transparent surfaces /
or semi transparent.
The goal of ZB lighting is to provide maximum contrast so that machine vision software can evaluate and make necessary judgment. On the image, the defect will be revealed in white on black.
It is important to pay special attention on lightings when inspecting objects with reflective surfaces. Reflections disrupt good images acquisitions and cause difficulties to identify defects. :
Machine vision systems are unable to process these unsatisfactory images with reflections and making it impossible to detect the defects (eg: scratch size, etc.).
Image with zebra mask ZB:
With zebra mask ZB, the lighting will be oriented and able to create light pattern. => The pattern becomes deformed when there are dents or bumps.
The size of the pattern (just like its geometry) must be adapted to the type of inspections and defects, we would be glad to assist you to define the suitable pattern.
This mask could help the image processing system to obtain following types of images during glass inspection:
With defect: Scratches
