Abstract: Aspects of the disclosure provide a first lens. The first lens can include an optically transparent member having a first surface and a second surface. The optically transparent member can be configured to receive light from a display device via the first surface. The received light exits the optically transparent member through the second surface. The first surface and the second surface of the optically transparent member can be aspheric. An in inner surface of the first surface is convex, and an outer surface of the first surface is concave. The inner surface is surrounded by the outer surface of the first surface. A thickness of a central region of the first lens can decrease from a center of the first lens, and
a thickness of a peripheral region of the first lens can increase from a boundary of the central region.

Abstract: An apparatus for detecting movements of a sample with respect to an objective includes imaging optics which include the objective, which have an image plane and which are configured to image light from at least one reference object that is connected to the sample arranged in front of the objective into reference object images in the image plane. The apparatus further includes a camera which is arranged in the image plane of the imaging optics and which is configured to record the reference object images at consecutive points in time, and an optical device arranged between the objective and the camera in a plane that is Fourier-conjugated with respect to the image plane. The optical device is configured to mask out low spatial frequencies of reference object images which the imaging optics image into the image plane.

Abstract: A display system includes a pixelated display being curved about at least one axis and including a plurality of groups of pixels; a plurality of light redirecting elements where each light redirecting element corresponds to a different group of pixels in the plurality of groups of pixels; and an optical lens system adapted to receive light emitted by the pixelated display and transmitted by the plurality of light redirecting elements. The optical lens system transmits at least a portion of the received light. For at least one pixel in the plurality of groups of pixels, the light redirecting element corresponding to the pixel reduces an angle between a central light ray emitted by the pixel and a chief light ray emitted by the pixel.

Abstract: A system comprising an illumination system to direct light from one or more light sources to a limiting output pupil of a projection optomechanical system, a liquid crystal on silicon display panel (LCOS) to modulate the light from the projection optomechanical system and to direct the modulated light back toward the projection optomechanical system, and an in-coupler to a combiner waveguide to receive the modulated light from the LCOS, after it passes through the projection optomechanical system. The system in one embodiment is designed so that the light that passes through the projection optomechanical system from the illumination system lands on the LCOS within the limiting output pupil of the projection optomechanical system.

Abstract: An optical component includes a first optical element having a curved first major surface; and an optical stack formed into a curved shape. The optical stack is bonded and conforms to the curved first major surface of the first optical element. The optical stack includes a reflective polarizer including a plurality of polymeric layers; and a non-adhesive flexible optical layer bonded to the reflective polarizer prior to forming the optical stack into the curved shape, such that the non-adhesive flexible optical layer bonded to the reflective polarizer improves a desired optical property of the reflective polarizer upon forming the optical stack into the curved shape relative to that of the reflective polarizer being formed into the curved shape without the non-adhesive flexible optical layer bonded to the reflective polarizer.
