Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include three lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged. The lens systems may include an aperture stop located behind the front vertex of the lens system, for example at the first lens element, and an optional infrared filter, for example located between the last lens element and a photosensor.

Abstract: A mobile device lens assembly having an electrically activated lens component with an electro-optic portion is disclosed. More particularly, embodiments of the mobile device lens assembly include the electro-optic portion and an interlock feature to engage a second lens element. The second lens element may have an interlock surface, which when engaged or mated with the interlock feature of the electrically activated lens component, may maintain alignment of the lens components along an optical axis. Other embodiments are also described and claimed.

Abstract: An optical system for a camera may include a lens group having a plurality of lenses, a prism, and an image sensor. The prism may be positioned, optically, between the plurality of lenses and the image sensor along the optical transmitting path of the light. The prism may include at least four surfaces, which may fold the light within the prism at least four times to guide the light from the plurality of lenses passing through the prism to the image sensor. The prism may include multiple prisms joined together using an optical cement. The prism may include one or more aperture masks inside the prism to reduce flare.

Abstract: Embodiments described herein relate to camera modules that incorporate an optically absorptive grating that is positioned and designed to reduce the impact of stray light on images captured by the camera modules. Specifically, the optically absorptive grating is configured to absorb light that is incident on the optically absorptive grating. The optically absorptive grating includes an array of protrusions, and in some instances may be part of a grating assembly that is coupled to an optical component.

Abstract: A device may include a light-folded projector that may include an infrared (IR) light emitter and a light folding element. The light folding element may receive IR light emitted from the IR light emitter and fold the IR light one or more times to guide the IR light passing through the light folding element to exit the device to an environment. The device may also include a detector that may detect and/or recognize an object in the environment using the IR light from the light-folded projector, and a front-facing camera to capture images of the environment in front of the device.

Abstract: A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (

Abstract: A lens system provides a zoom function (variable magnification) in a low profile camera (lens system height less than or equal to 6 mm), which may be in a cellular phone. The lens system includes at least three movable lens groups that are movable along a common optical axis. Each of the three movable lens groups is coupled to a corresponding actuator. Responsive to a request for a change in focal length or magnification, a controller sends a corresponding signal to each of the actuators that move the corresponding lens group by a corresponding distance in a corresponding direction. The various movable lens groups may be moved by different distances and in different directions of movement. An f-number of the lens system is less than f/3.0. Focusing of an image cast onto an image sensor is accomplished by adjusting the position along the optical axis of one of the movable lens groups.

Abstract: Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.
