  • Method of Manufacturing an Optical System
    Publication number: 20130218533
    Abstract: A method of calculating an optical system (OS), the optical system (OS) being identified by a function (OF), the optical system (OS) having a first part (F1) defined by a first equation (EF1) and a second part (F2) defined by a second equation (EF2), the method performed by: a generating step (GEN), in which a virtual optical system (VOS) is used to generate a virtual function (VOF); a modification step (MOD), in which the virtual function (VOF) is modified so as obtain the function (OF); a calculation step (CAL), in which the second equation (EF2) is calculated from the function (OF), and the first equation (EF1). A method of manufacturing an optical system (OS) is also disclosed.

  • Fringe deflectometry apparatus and method
    Patent number: 6043885
    Abstract: A fringe deflectometry apparatus illuminates an optical component to be measured using radiation with a known wavefront, deflects the radiation after it has been reflected or transmitted by the optical component to be measured, and materializes a reference ray. Transverse aberration of the reference ray after reflection or transmission by the optical component is measured. A deflectometry method using the apparatus enables an absolute phase reference to be provided.
