Abstract: Single fold optical systems that include a power prism and a lens stack including two or more refractive lens elements. The single fold optical system may provide a long mechanical back focus without increasing the Z-height of the optical system. Providing power on the prism may reduce the optical total length and reduce the X-length of the optical system. The single folded optical systems may provide reduced Z-axis height and reduced X-axis length when compared to conventional double folded optical systems with similar optical characteristics. In addition, the optical systems may include an anamorphic lens that is oriented to correct for astigmatism caused by surface errors of the reflective surface of the prism.

Abstract: An optical component includes a mask defining a light blocking portion and a light transmitting portion of the optical component. The light blocking portion is separated from the light transmitting portion by one or more mask edges, at least one of which is defined by an apodized pattern. The apodized pattern of the mask edge reduces diffraction and thus flare caused by the mask.

Abstract: A freeform folded optical system that include two freeform prisms with optical power. At least one of the freeform prisms is configured to fold the optical axis twice. Thus, embodiments of the freeform folded optical system fold the optical axis three or four times. Folding the optical axis three or four times in the freeform prisms allows for long focal lengths required for telephoto lens applications without requiring additional lens elements between the prisms. In addition, the configuration of the freeform folded optical system provides reduced Z-axis height when compared to conventional folded lens systems with similar optical characteristics.

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: 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.
