WebKnown as phototherapy, the use of light in medical treatment is producing surprisingly successful results in the treatment of a variety of ailments from topical infections and chronic wounds to autoimmune and chronic degenerative diseases, says Chukuka S. Enwemeka, dean of the University of Wisconsin–Milwaukee’s College of Health Sciences. There are four main types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers (named for the instrument's inventor and based on Ernst Abbe's original design of the 'critical angle') and inline process refractometers. There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases. In laboratory medicine, a refractometer is used to measure the total plasma protein in a blood sa…
