Carl A. Vossberg Jr.
Carl A. Vossberg, Jr., (born July 16, 1918 - March 9, 2008) was an American electrical engineer, inventor, and entrepreneur in the electronic instrumentation industry. He is known for more than 30 technical patents in the area of refractometry, measurement, and control. Vossberg also founded Electron-Machine Corporation, the company responsible for the introduction of inline process refractometers as a measuring system for the Paper engineering, pulp & paper, food, and Chemical industry, chemical processing industries. Early life and education Vossberg began his college education at the City College of New York, City College of the City of New York (CCNY), studying electronics, and was awarded a BEE in Electrical Engineering from CCNY and a MS in Electrical Engineering (EE) from Columbia University. He also attended Massachusetts Institute of Technology. During WWII, Vossberg worked for the U.S. Office of Strategic Service (now CIA) participating in the development of remote rad ...

Refractometry
Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical property, physical properties) in order to, for example, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they are also used to measure gases and solids; such as glass and gemstones. The RI of a substance is strongly influenced by temperature and the wavelength of light used to measure it, therefore, care must be taken to control or compensate for temperature differences and wavelength. RI measurements are usually reported at a reference temperature of 20 degrees Celsius, which is equal to 68 degrees Fahrenheit, and considered to be room temperature. A reference wavelength of 589.3 nm (the sodium D line) is most often used. Though RI is a dimensionless quantity, it is typically reported as nD20 (or n), where the "n" represents refractive inde ...
