摘要： A method for making a gradient index infrared transmitting optic by thermally treating a preform, where the preform comprises two or more infrared transmitting glasses having different compositions and optical properties, where there is an interface between adjacent glasses, where during the thermal treatment one or more chemical elements from the glasses diffuses through one or more interface resulting in a diffused gradient index optical element comprising a gradient in the chemical element concentration, and where the optical element has a gradient in refractive index and dispersion. Also disclosed is the related infrared transmitting optical element made by this method.

摘要： The invention discloses an eight-piece optical lens for capturing image and an eight-piece optical module for capturing image. In order from an object side to an image side, the optical lens along the optical axis comprises a first lens with refractive power; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; a fifth lens with refractive power; a sixth lens with refractive power; a seventh lens with refractive power; and an eighth lens with refractive power; and at least one of the image-side surface and object-side surface of each of the eight lens elements can be aspheric. The optical lens can increase aperture value and improve the imagining quality for use in compact cameras.

摘要： The invention relates to an optical system with mirrors for an image sensor, comprising two symmetrical concave mirrors (20a, 20b) arranged in the same plane and having parallel optical axes (Oa, Ob); and an image sensor array (24) arranged in front of the mirrors and having two opposing edges which are respectively substantially adjacent to the optical axes of the two mirrors. The image sensor can be attached to an opaque mask (28) comprising, on the periphery of the image sensor, an entrance pupil (26) in front of each mirror (20), contained in the surface of the mirror extending beyond the image sensor.

摘要： A method for manufacturing an integrated circuit includes scanning a wafer with respect to a catadioptric projection objective and imaging a pattern on a mask onto a wafer while scanning the wafer. The imaging includes illuminating the mask with radiation; imaging, using the radiation, the pattern into a first intermediate image, the first intermediate image to a second intermediate image, and the second intermediate image into an image field arranged in an image surface where the wafer is arranged; and, manipulating one or more of optical elements while scanning the wafer to reduce errors in the image at the image field. A concave mirror arranged in a region of a pupil surface reflects the radiation. The projection objective also includes mirrors to deflect the radiation from the object field towards the concave mirror and to deflect the radiation from the concave mirror towards the image field. The deflection mirrors are mechanically coupled to a displacement device arranged to displace the first and second deflection mirrors.

摘要： Infrared cameras can include an infrared sensor and an infrared lens assembly defining an optical axis. A camera can include an inner gear engaging the infrared lens assembly and a focus ring that engages the inner gear. The inner gear can engage the focus ring and the infrared lens assembly such that rotation of the focus ring about its central axis can cause the rotation of the infrared lens assembly about its optical axis, which may be offset from the central axis of the focus ring. The camera can include a sensor can threadably engaging the infrared lens assembly and fixed relative to the infrared sensor such that rotation of the infrared lens assembly causes the infrared lens assembly to move relative to the infrared sensor. The sensor can support other components such as a visible light lens assembly or a laser within a perimeter of the focus ring.
