In 1876, [[Ernst Gundlach]] joined the company as it began to manufacture [[microscope]]s. Later that year, the Bausch & Lomb Optical Company won a distinction at the Philadelphia [[Centennial Exposition]]. The company also produced [[photographic lens]]es (1883), [[spectacle lens]]es (1889), [[microtome]]s (1890), [[binoculars]] and [[telescope]]s (1893).<ref name="LOMBbio">{{cite web|url=http://www.spartacus.schoolnet.co.uk/USAlomb.htm |title=Henry Lomb bio |archiveurl=https://web.archive.org/web/20071026134714/http://www.spartacus.schoolnet.co.uk/USAlomb.htm |archivedate=2007-10-26 }}</ref> From 1892 in cooperation with [[Carl Zeiss AG|Zeiss]] in Germany, the company produced optical [[Lens (optics)|lenses]].
