Title: SYSTEM AND METHOD FOR CHARACTERIZING, DESIGNING AND/OR MODIFYING OPTICAL PROPERTIES OF A LENS
Abstract:
The system comprising an illuminating unit (1, 11, 21) to emit a light beam with a specific spectral content onto an object test (OT); an optical system (OP_S) to form an image of said object test (OT) at an image plane (Ο'), said optical system (OP_S) including a first optical unit (4), a first element, a second element and a supporting structure (17) to hold up a lens (7) the optical properties of which have to be characterized, designed and/or modified, wherein the optical unit (4) keeps the state of polarization of the light beam passing through it; and an acquisition system (9) configured to record said image formed at said image plane (Ο') by converting light intensity thereof in an electrical signal and by digitizing said electrical signal into a corresponding digital image of the image plane (Ο').
