OPTICAL ELEMENT, METHOD FOR MANUFACTURING SUCH AN ELEMENT AND A METHOD FOR ALIGNING A LIGHT BEAM AND SUCH AN ELEMENT

摘要

Optical element, provided with a receiving plane (10) comprising a receiving section (11) for receiving at least one light beam (2), wherein the receiving plane (10) is provided with at least one light-detection element (3) being arranged to detect whether at least part of said light beam is projected thereon.Further, the invention relates to a method for manufacturing an optical element, wherein the optical element substrate is provided with the at least one light-detection element, using at least one thin layer deposition technique.
