Excellent guide to machine vision lighting

From ‘Vision & Sensors’ mag comes a first class primer on illumination for machine vision. In this lengthy and detailed article Brent Evanger of Banner Engineering discusses the importance of lighting, as well as the options available, (LED, fluorescent, halogen,) and lighting geometry, (darkfield, brightfield, backlighting.) It’s a well written piece with good information for both the vision ‘newbie’ and the experienced pro.

And while I’m praising the article, let me sling more praise in Banner’s direction. It’s no secret that I’m a fan of their low end, inexpensive, vision sensors. Yes, they are limited in their functionality, but the Banner software is easy to use – in fact almost intuitive – and the price is right. If you’re considering a vision system from Keyence or Omron you should also look at Banner. Check them out at
