Abbe Refractometer

Description
Bausch & Lomb began making refractometers when World War I limited the import of European instruments coming into the United States. This Abbé-type refractometer is marked "Bausch & Lomb Optical Company Rochester N.Y. Ser. No. 77381 USA Pat. No. 2,080,841." Miles E. Hess Jr. donated it to the Smithsonian. The referenced patent, issued to Harold Straat in 1937 and assigned to Bausch & Lomb, described a new prism system and box for refractometers.
