Innovative precision instruments for over 150 years.

The Reichert® tradition of precision instruments has a proud lineage of innovations that began with the first American made microscope by Charles Spencer in 1838, and the founding of the American Optical (AO) Company in 1869. For the past 150 years, we have created almost every breakthrough in refractometry that has become a standard of the industry. Although our name has changed over the years, our commitment to innovation and quality continues in every product we design and build.

Today, Reichert is the only United States manufacturer that designs, manufactures, sells and services high quality optical refractometers for a wide range of industries.
