Optical System Including Light Control Film and Fresnel Lens - A simplified explanation of the abstract

This abstract first appeared for US patent application 18557199 titled 'Optical System Including Light Control Film and Fresnel Lens

The optical system described in the patent application consists of an optical film curved around a first axis and a light control film curved around the same axis, covering the optical film. The optical film includes a microstructured surface that forms a linear Fresnel lens, while the light control film has optically absorptive regions.

• The optical film features a microstructured surface that creates a linear Fresnel lens with multiple Fresnel elements.
• The light control film contains optically absorptive regions that help control the light passing through.
• Both films are curved around the same axis, enhancing their optical properties.
• The system includes reflection mitigation elements to improve overall performance.
• The design allows for precise control and manipulation of light, making it suitable for various applications.

Original Abstract Submitted

An optical system includes an optical film curved about a first axis and a light control film curved about the first axis and substantially coextensive with the optical film. The optical film includes a first layer including a microstructured first major surface where the microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending along the first axis. The first major surface of the optical film faces the light control film. The light control film includes a plurality of spaced apart optically absorptive regions extending along the first axis and along a direction substantially normal to a major surface of the light control film. At least one of the optical film or at least one layer disposed between the optical film and the light control film includes at least one reflection mitigation element.
