Abstract: An optical element includes an optical surface configured to receive light at a predetermined wavelength in a range from about 400 nm to about 1000 nm. The optical surface is defined by a vertical axis and a horizontal axis defining four Cartesian quadrants sequentially numbered in a counter-clockwise direction. A first longitudinal section of the optical surface is centered on the vertical axis and a second longitudinal section of the optical surface is centered on the horizontal axis. The first and second longitudinal section each extend across opposite edges of the optical surface and have a same substantially uniform retardance for substantially normally incident light. The optical element includes four discrete retarder sections. Each retarder section is disposed on a respective Cartesian quadrant of the optical surface and has a retardance difference from the substantially uniform retardance of the optical surface that is greater than zero.

Abstract: A reflective polarizing imaging lens includes at least one optical film having an active area that is curved in two orthogonal directions. Edges of the optical film are arranged to form seams between segments of the optical film in the active area of the reflective polarizing imaging lens.

Abstract: Optical films and polarizing beam splitters including the optical films are described. In some cases, the optical film includes a first optical stack disposed on, and spaced apart by one or more spacer layers from, a second optical stack, each optical stack comprising a plurality of polymeric interference layers reflecting and transmitting light primarily by optical interference in a same predetermined wavelength range. Each optical stack has interference layers closer to the one or more spacer layers that reflect longer wavelengths and interference layers farther from the one or more spacer layers that reflect shorter wavelengths.

Abstract: An optical stack including a first reflective polarizer adhered to a second reflective polarizer is described. For normally incident light and each wavelength in a same predetermined wavelength range, each reflective polarizer transmits at least 80% of light polarized along a pass axis of the reflective polarizer and reflects at least 90% of light polarized along an orthogonal block axis of the reflective polarizer. Each reflective polarizer includes a plurality of polymeric interference layers reflecting and transmitting light primarily by optical interference in the predetermined wavelength range. A separation between the two polymeric interference layers in the plurality of polymeric interference layers farthest from each other are d1 and d2 for the respective first and second reflective polarizers, d1 is at least 20% less than d2. Polarizing beam splitters including the optical stack and optical systems including the polarizing beam splitter are described.

Abstract: Optical systems for displaying an image are described. The optical systems include a first and second optical lenses separated by air. A partial reflector is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature in a range from 20 mm to 200 mm. A reflective polarizer is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature greater than about 500 mm. A retarder layer is disposed between the reflective polarizer and the partial reflector. The first optical lens can have an optical birefringence of less than 15 nm/cm and the second optical lens can have an optical birefringence of greater than 15 nm/cm. A method of fabricating an optical assembly is described.

Abstract: An optical system (200) provides wide field of view in a compact system having a low profile. The optical system (200) includes a display (10), a reflective polarizer (60), a minor (100), and a partial reflector (110), to provide a folded optical path between an image source and an eye of a viewer (30).

Abstract: A bi-focal prescription eyewear lens includes a substrate and a reflective polarizer, or a partial reflector, bonded to the substrate. A reflective polarizer substantially transmits light having a first polarization state and substantially reflects light having an orthogonal second polarization state. The bi-focal optical lens has a first focal length for light having the first polarization state and a second focal length for light having the second polarization state. The first focal length is longer than the second focal length. Without the reflective polarizer or partial reflector, the bi-focal optical lens would have a single focal length. Eyeglasses can include the bi-focal prescription eyewear lens.
