2-4-1 Machine Vision Lighting Principles
Proper lighting is critical to the success of a machine vision application. Depending on the requirements of
your application, you may also need external lighting from Omron 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.
