Bausch & Lomb and Konica

14 and 12 researched events on one shared scale. Bausch & Lomb 1853–present, Konica 1873–present.

The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
