Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have a pixel array that produces light associated with images. The display system may also have a linear polarizer through which light from the pixel array passes and a quarter wave plate through which the light passes after passing through the quarter wave plate. The optical system may be a catadioptric optical system having one or more lens elements. The lens elements may include a plano-convex lens and a plano-concave lens. A partially reflective mirror may be formed on a convex surface of the plano-convex lens. A reflective polarizer may be formed on the planar surface of the plano-convex lens or the concave surface of the plano-concave lens. An additional quarter wave plate may be located between the reflective polarizer and the partially reflective mirror.

Abstract: A head-mounted device may have optical modules that present images to the user's left and right eyes. The optical modules may move with respect to each other to accommodate different user interpupillary distances. Each optical module may have a lens barrel, a display coupled to the lens barrel that generates an image, and a lens mounted to the lens barrel through which the image is viewable from an eye box. The lens may be a multi-element lens formed from molded lens elements such as molded polymer lens elements. A lens element may be provided with protrusions that form lens tabs. The lens tabs may have coplanar lens tab surfaces that mate with corresponding coplanar mounting surfaces in the lens barrel. Alignment marks may be formed on the protrusions and/or other portions of the lens.

Abstract: A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. The head-mounted device may have a left lens that directs images from the left portion of the display to a left eye box and a right lens that directs images from the right portion of the display to a right eye box. Each lens may include a lens element that is coupled to the display. The lens element may be attached to the display with a layer of optically clear adhesive or the lens element may be formed from gel that directly contacts the display. The lens element attached to the display may have protrusions or recesses to accommodate input-output components. A single lens element may be attached to both the left and right portions of the display.

Abstract: A head-mounted device may include a display system and an optical system in a housing. The display system may have displays that produce images. The optical system may have Fresnel lenses through which a user of the head-mounted device may view the images. The Fresnel lenses may have concentric rings with slope facets and draft facets angled parallel to the chief rays. Light scattering in the Fresnel lenses may be reduced by coating the draft facets with opaque masking material and/or by aligning concentric rings of the opaque masking material that are supported on a transparent substrate with the draft facets. A central portion of the Fresnel lens that is free of facets may be enlarged to reduce scattering. The Fresnel lenses may have wedge-shaped cross-sectional profiles and may have outer portions that are thicker than inner portions. Gradient-index material may be used in forming the Fresnel lenses.

Abstract: An electronic device may include a display with a concave surface. A linear polarizer may be formed on the concave surface. A quarter wave plate may receive light from the linear polarizer. A catadioptric lens may have first and second lens elements. The first lens element may have first and second opposing surfaces. The second lens element may have opposing third and fourth surfaces. The first surface may be convex and may face the display. The fourth surface may be concave. The second surface may be concave. The third surface may be convex and may match the second surface. An additional quarter wave plate may be formed as a coating on the third surface. A partially reflective coating may be formed on the first surface. A reflective polarizer may be formed as a coating on the fourth surface. An additional polarizer may be formed on the reflective polarizer.

Abstract: A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. In one example, the optical system includes a single lens element and a retarder that is coated on a curved surface of the lens element. The retarder may be coated on an aspheric concave surface of the lens element. In another example the retarder may be coated on an aspheric convex surface of the lens element. One or more components of the optical system may be formed using a direct printing technique. This may allow for one or more adhesive layers and one or more hard coatings to be omitted from the optical system. A lens element may be directly printed on the display system to improve alignment between the optical system and the display system.
