Abbe Refractometer


Bausch & Lomb began making refractometers when World War I limited the import of European instruments coming into the United States. The inscription on this Abbé-type refractometer reads "Bausch & Lomb Optical Company Rochester N.Y. Ser. No. 77381 USA Pat. No. 2,080,841." The referenced patent, issued to Harold Straat in 1937 and assigned to Bausch & Lomb, described a new prism system and box for refractometers.
