The lens alignment adjustment device includes: a base plate which is retained in a predetermined posture with respect to the projector; and a lens fixing plate to which the projection lens is fixed. The lens fixing plate is rockably coupled to the base plate through intermediation of a first center pin orthogonal to an optical axis of the projection lens. First adjusting means for setting an inclination angle of the lens fixing plate with respect to the base plate about the first center pin is provided.Type: GrantFiled: January 13, 2017Date of Patent: February 25, 2020Assignees: THK CO., LTD., SEIKO EPSON CORPORATIONInventors: Noriaki Chikamoto, Hiroyuki Furui, Akira Nemura

Patent number: 10423082Abstract: A microlithographic apparatus comprises an optical wavefront manipulator. The latter includes an optical element and a gas-tight cavity that is partly confined by the optical element or contains it. A gas inlet device directs a gas jet towards the optical element. The location, where the gas jet impinges on the optical element after it has passed through the cavity, is variable in response to a control signal supplied by a control unit. A gas outlet is in fluid connection with the vacuum pump so that, upon operation of the vacuum pump, the pressure within the cavity is less than 10 mbar even if the gas jet passes through the cavity.Type: GrantFiled: October 9, 2014Date of Patent: September 24, 2019Assignee: Carl Zeiss SMT GmbHInventor: Leonid Gorkhover

Patent number: 10325376Abstract: Systems and methods for machine vision are presented. Such machine vision includes ego-motion, as well as the segmentation and/or classification of image data of one or more targets of interest. The projection and detection of scanning light beams that generate a pattern are employed. Real-time continuous and accurate spatial-temporal 3D sensing is achieved. The relative motion between an observer and a projection surface is determined. A combination of visible and non-visible patterns, as well as a combination of visible and non-visible sensor arrays is employed to sense 3D coordinates of target features, as well as acquire color image data to generate 3D color images of targets. Stereoscopic pairs of cameras are employed to generate 3D image data. Such cameras are dynamically aligned and calibrated. Information may be encoded in the transmitted patterns. The information is decoded upon detection of the pattern and employed to determine features of the reflecting surface.Type: GrantFiled: December 17, 2018Date of Patent: June 18, 2019Inventor: Gerard Dirk Smits
