摘要： A reflective mobile phone lens, comprising a semi-permeable semi-reflecting mirror (5), a concave spherical reflecting mirror (4) and a mobile phone (1) screen; the mobile phone (1) screen serves as a display screen to display an image; light passes through the semi-permeable semi-reflecting mirror (5) and arrives at the concave spherical reflecting mirror (4), and then is reflected by the concave spherical reflecting mirror (4) back to the semi-permeable semi-reflecting mirror (5), and is reflected by the reflective surface of the semi-permeable semi-reflecting mirror (5) onto the mobile phone (1) screen. The mobile phone lens enables watching an online movie or playing a virtual reality game on the mobile phone (1) to have a good effect like watching a movie on a big screen in a cinema.

摘要： This invention provides a field of view expander (FOVE) removably attached to a vision system camera having an image sensor defining an image plane. In an embodiment the FOVE includes first and second mirrors that transmit light from a scene in respective first and second partial fields of view along first and second optical axes. Third and fourth mirrors respectively receive reflected light from the first and second mirrors. The third and fourth mirrors reflect the received light onto the image plane in a first strip and a second strip adjacent to the first strip. The first and second optical axes are approximately parallel and a first focused optical path length between the scene and the image plane and a second focused optical path between the image plane and the scene are approximately equal in length. The optical path can be rotated at a right angle in embodiments.

摘要： A catadioptric projection objective has a first objective part, defining a first part of the optical axis and imaging an object field to form a first real intermediate image. It also has a second, catadioptric objective part forming a second real intermediate image using the radiation from the first objective part. The second objective part has a concave mirror and defines a second part of the optical axis. A third objective part images the second real intermediate image into the image plane and defines a third part of the optical axis. Folding mirrors deflect the radiation from the object plane towards the concave mirror; and deflect the radiation from the concave mirror towards the image plane. The first part of the optical axis defined by the first objective part is laterally offset from and aligned parallel with the third part of the optical axis.

One example of a reflective optical telescope includes a primary mirror positioned along a linear axis extending between an entrance aperture and an image plane, configured to receive optical radiation via the entrance aperture, a secondary mirror positioned along the linear axis and configured to receive the optical radiation from the primary mirror and to reflect the optical radiation in a direction of the primary mirror, wherein the optical radiation received by the primary mirror is unobscured by the secondary mirror, a tertiary mirror positioned along the linear axis and configured to receive the optical radiation from the secondary mirror and reflect the optical radiation in a direction of the primary mirror, and a quaternary mirror positioned along the linear axis, configured to receive the optical radiation from the tertiary mirror and reflect the optical radiation to the image plane.

摘要： There is provided a projection optical system that projects an image of an object onto an image plane. The projection optical system includes an imaging optical system including a first concave mirror, a convex mirror, and a second concave mirror; an optical member having a first reflecting surface and a second reflecting surface each redirecting an optical path; and a supporting member that supports the convex mirror. The first reflecting surface, the first concave mirror, the convex mirror, the second concave mirror, and the second reflecting surface are provided in that order in a direction of travel of light from an object plane. The optical member has a through hole having an opening on a side facing the convex mirror. The supporting member extends through the through hole and from the opening to the convex mirror.

摘要： An imaging optical unit serves within a metrology system for examining a lithography mask. The lithography mask can be arranged in an object field of the imaging optical unit. The object field is defined by two mutually perpendicular object field coordinates. The imaging optical unit has an aperture stop of which the aspect ratio in the direction of the two object field coordinates differs from 1. This results in an imaging optical unit which can be used for the examination of lithography masks that are designed for projection exposure with an anamorphic projection optical unit.

摘要： A method of calibrating a reflective focusing optics to provide a system that minimizes the effect of multiple beam reflections therewithin on polarization state reflective optics system that preferably requires the presence of both convex and a concave mirrors that have beam reflecting surfaces, the application of which achieves focusing of a beam of electromagnetic radiation onto a sample, (which can be along a locus differing from that of an input beam), with minimized effects on a polarization state of an input beam state of polarization based on adjusted angles of incidence and reflections from the various mirrors involved.
