Determining whether to apply lights in a bright field versus dark field geometry is one of the more difficult decisions facing Machine Vision engineers. Both techniques have advantages and disadvantages: in this blog, we will concentrate on a comparison between the two using common vision applications.

In machine vision, backlighting is one of the most common and useful lighting techniques. However, incorporating backlighting into machine vision systems can be difficult, primarily because component placement geometry requires access to the part top and bottom (or front and back) for the camera and backlight.

Manufacturers and OEMs seeking to create a machine vision system to automate production or improve product quality are faced with numerous choices. Knowledge of the types of systems and the array of options can be confusing. There are so many factors to consider in keeping costs low without comprising inspection robustness. Precision Lighting Matters In […]

Machine vision lighting includes both industrial and non-industrial applications where a combination of hardware and software provide operational guidance to devices in the execution of their functions based on the capture and processing of images. Lighting is critical to render visibility to the object to be imaged; other necessary elements are optics to focus the […]
