Modulation Transfer Function (MTF)

The Modulation Transfer Function (MTF) curve is an information-dense metric that reflects how a lens reproduces contrast as spatial frequency (resolution) varies. MTF curves can be used to compare the performance of multiple lenses and can help determine if an application is actually feasible with the respective lens.

Ruggedization of imaging lenses

Imaging lenses used in many industrial machine vision applications have special requirements beyond those of standard imaging lenses. The lenses used in factory automation, robotics, and industrial inspection have to work in specific and demanding environments, which could involve vibrations, shocks, temperature changes, and contaminants. Because of these environmental requirements, new classes of ruggedized lenses are being designed specifically to work in a multitude of different scenarios, therefore creating different types of ruggedization. There are three distinct types of ruggedization available: Industrial Ruggedization, Ingress Protection Ruggedization, and Stability Ruggedization.
