SOME APPLICATIONS OF THE MURTY INTERFEROMETER - A REVIEW

Several applications of the Murty interferometer in the testing of opt ical systems and components are reviewed in this article. The interfer ometer has applications in the testing of lenses, spherical mirrors, p araboloidal mirrors and parallel plates. The interferometer can also b e used for the determination of homogeneity of optical materials, meas urement of refractive indices of glasses and liquids, measurement of r adii of curvature and location of cardinal points, checking the laser beam collimation, determination of the power of ophthalmic lenses, mea surement of refractive indices of simple lenses, measurement of birefr ingence of optical materials, thermal expansion coefficient of metalli c bars and optical distortion in transparencies or glass windows.
