Abstract
THE optical system used by Michelson in his interferometer, which was applied by him to so many important purposes, has since 1917 been gradually coming into use in a modified form as a routine test in the manufacture of lenses and prisms. The various forms in which it has been used have been the subject of a series of patent applications1 and have been described in various technical papers2, which are of little interest except to specialists in optical manufacture. The general principles of the instrument may appeal to a wider circle and are sufficiently well illustrated by the two simplest forms Bailed, respectively, the prism and the lens interferometer.
