Miyachi's LMV1000G is a laser marker with 532 nm-wavelength laser output for marketing plastics and previous metals. Units reportedly make machine and human-readable marks on gold-plated electronic components without removing any of the gold, which preserves the plating's corrosion resistance and electrical properties. Units produce line widths as small as 20µ, character sizes down to 100µ, and data-matrix codes with 20µ cell sizes using standard-length lenses.
