As the leading innovator in the field of precise illumination for machine vision, Northeast Robotics has mastered the highly complex nature of machine vision illumination.
Cameras see light as it is reflected from an object.
Light is reflected differently from a metal ball than from a flat white label or a printed circuit board. The purpose of machine vision illumination is to control how the object appears to the camera. With these differences in mind, NER studies the geometric patterns of the light reflected from the part and designs lighting systems to control glare and reflection. With this approach, specular surfaces perpendicular to the camera appear illuminated, while surfaces at an angle to the camera appear dark. Non-specular surfaces absorb light and appear dark.
