Abstract: An optical film and a polarizing beam splitter (PBS) including the optical film is described. The optical film includes a first optical stack disposed on, and spaced apart by one or more spacer layers from, a second optical stack. When the optical film is disposed between, and adhered to, hypotenuses of first and second prisms to form a PBS and a cone of light is incident on the PBS making an incident angle of about 40 to 50 degrees with the optical film, the PBS has: an average optical reflectance Rs greater than about 95% for a first polarization state; an average optical transmittance Ts less than about 0.012% for the first polarization state; an average optical transmittance Tp less than about 98.5% for a second polarization state; and an average optical reflectance Rp less than about 0.25% for the second polarization state.

Abstract: An optical lens assembly includes a middle-lens disposed between, and bonded to, an eye-lens and a display-lens, each of the lenses including an active lens region defined as a maximum lens region configured to transmit an image emitted by a display therethrough. A first at least partially light transmitting film is disposed on, and substantially conforming to, a curved first major surface of the eye-lens. A second at least partially light transmitting film is disposed between, and substantially conforming to each of, a curved second major surface of the eye-lens and a curved first major surface of the middle-lens. A first retarder layer is disposed between, and substantially conforming to each of, a second major surface of the middle-lens and a first major surface of the display-lens; and a third at least partially light transmitting film is disposed on, and substantially conforming to, a curved second major surface of display-lens.

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: The disclosure describes an example vehicle assistance system including a light sensor, a pixelated filter array adjacent the light sensor, and a full-field optically-selective element adjacent the pixelated filter array. The optically-selective element is configured to selectively direct an optical component of light incident on the optically-selective element across the pixelated filter array to the light sensor.

Abstract: An optical system for displaying first and second images to a viewer is provided. A reflective polarizer is disposed between the second display and the viewer and is oriented obliquely relative to the first display. An optical stack including a partial reflector and a retarder layer is disposed between the reflective polarizer and the second display. The reflective polarizer reflects at least 70% of the incident light having a first polarization state and transmits at least 60% of the incident light having an orthogonal second polarization state. The partial reflector reflects at least 70% of the incident light for each of the polarization states. For each of the first and second polarization states and for each of a blue-green wavelength and a green-red wavelength the reflective polarizer transmits at least 70% of the incident light and the partial reflector transmits at least 60% of the incident light.
