Keeping it lean, mean, and simple
Use older technology to balance your budget.

Buyers of machine-vision components and systems are feeling the budget pinch. As a result of the continuing economic crunch, they have a lot less time or money than just a year or two ago.
People in the industry are coping by keeping things simple. One way to do that is to use older technology and squeeze as much benefit out of it as possible. Analog cameras, for example, have been around for decades in semiconductor and electronics inspection, and the transition from analog to digital technology has accelerated in the last few years ("Analog cameras still play a role"). Yet, analog is still the camera technology of choice in many areas where digital cameras aren’t really needed, and for many application engineers, analog cameras are easier and simpler to install.

Another way to keep things simple is to design only the inspection system your production line, and your customers, need. Cognex’s customer Schneider Electric did exactly that for its Osiswitch Compact line of limit switches ("Vision system enables zero defects"). In the process, Schneider Electric solved some complex inspection problems and reduced its customer return rate to zero parts per million, a figure often associated with much more complex and expensive systems than this two-camera, five-light-source, one-laser configuration.
