Why does a lens with no moving parts often outperform a motorized zoom in a high-speed sorting line? And why do the tightest tolerance quality control applications in electronics, automotive, and pharmaceutical manufacturing still rely on this seemingly simple optical design rather than something more adjustable? The answers lie in the mechanica…
