Abstract:
     This invention discloses a method and a device for applying an interferometer to determine focusing faces of an optical system accurately, in which, the working principle is that the standard light emitted by a laser interferometer is reflected back to the interferometer after passing through a tested optical system and the focusing face of an optical system is determined by the principle that it is easy for it to get interference fringes at the cat-eye position so as to increase the location accuracy of the focusing faces of an optical system.
