Machine Vision Lighting Principles
Proper lighting is critical to the success of a machine vision
application. The Vision MINI features integrated lighting (built-in red
LEDs @ 617nm). Depending on the requirements of your application,
you may also need to add external lighting from Microscan’s
NERLITE family of machine vision lighting products.
Consider the following when setting up your application:
– Is the surface of the object flat, slightly bumpy, or very bumpy?
– Is the surface matte or shiny?
– Is the object curved or flat?
– What is the color of the object or area being inspected?
– Is the object moving or stationary?
Machine vision lighting should maximize contrast of the areas or features
being inspected while minimizing the contrast of everything else.
