ADASとロボットビジョンの要件はどのように共通しているのか？
Both automotive ADAS and mobile robots require ruggedized optics that maintain performance under vibration and temperature cycling. All-glass assemblies remove one drift term, polymer index and shape change, but focus stability over temperature comes from the design as a whole: glass choices balancing CTE and dn/dT, element spacing, and barrel behavior, confirmed by measuring focus and MTF on the assembled lens over temperature.
Thread-locked M12 mounts keep the lens-to-holder joint from backing off under road vibration and warehouse floor impacts. Holding focus and alignment through those events also depends on internal element retention and the module's own mounting, so reliability testing runs on assembled lenses rather than being inferred from the thread lock.
