Machine vision cameras can be set up in production lines or mounted on moving parts such as robot arms in order to acquire images in industrial settings for such purposes as checking manufacturing tolerances, localization and geometrical measurement of objects, remote monitoring, etc. Such cameras can be integrated into an environment with external lighting or provide their own light source, and may cover different spectral bandwidths (RGB, IR, UV, etc) and sensitivities to light.

They are typically expected to be powered on and available at all times for extended timespans measured in years, sometimes in difficult conditions (extreme heat or cold, vibrations, etc). Controlling the image quality of the camera system is critical to guaranteeing accuracy and repeatability of the installation, as well as to quickly identifying failure modes over time and thus avoiding productivity losses. Analyzer’s flexible testing charts come in different sizes, from close-range inspection charts that can be integrated inside an inspection line to large-scale charts mounted on walls or on easy-to-move wheeled easels.
