JML Optical was having most of its custom lenses and other optical components built in China.
But since new owners took over in 2011, JML Optical has participated in a growing trend in manufacturing: bringing production back to the United States, where it’s easier to manage customers’ increasingly exact tolerances for variation.
Currently about half of JML Optical’s manufacturing takes place at the plant in East Rochester.
JML Optical specializes in custom manufacturing of optical products, ranging from single glass lenses to multi-part scopes that could be found in blood analyzing equipment or the 360-degree vision systems of U.S. Army tanks.
