Harsh Environments Call For Athermalized Imaging Lenses Jul 15, 2021 — All matter expands and contracts in response to changes in temperature — imaging lenses are no exception. Standard-design lenses developed for machine vision systems perform well in temperature-controlled environments in applications where temperatures shift only slightly. But in high-performance vision systems that are subjected to extreme or wide shifts in temperature — such as autonomous systems operating outdoors, high-performance factory automation, and aerospace systems — the use of...
