Abstract: In some embodiments, an auxiliary optical system comprises an adapter that is either separable from or unitary with a retainer. The adapter permits the retainer to removably attach to a plurality of mobile electronic devices of different sizes. In some embodiments, an auxiliary optical system comprises a mounting component configured to removably attach to a mobile electronic device and to a base which includes a plurality of attachable subcomponent securement members. Each securement member is configured to receive at least one optical element. In some embodiments, an auxiliary optical system comprises a retainer component configured to removably receive an optical element and to removably receive a non-optical component and/or an electronic component.

Abstract: A multi-lens system can be configured to be selectively attachable to a mobile electronic device having a user-facing onboard camera lens and an outward-facing onboard camera lens. The multi-lens system can attach to the mobile electronic device in at least a first position and a second position. The first lens component in the first position is configured to be in optical alignment with the user-facing onboard camera lens and simultaneously the second lens component is configured to be in optical alignment with the outward-facing onboard camera lens. The first lens component in the second position is configured to be in optical alignment with the outward-facing onboard camera lens and simultaneously the second lens component is configured to be in optical alignment with the user-facing onboard camera lens. A portable attachment accessory can be configured to be selectively attachable to a lens system that is configured to receive a portion of a mobile electronic device.

Abstract: Examples of cases and other accessories for mobile electronic devices are provided. Some cases are provided to protect mobile electronic devices from unintended forceful contact that could otherwise cause damage to the mobile electronic devices and/or to protect the mobile electronic devices against unwanted and potentially damaging ingress of harmful materials, such as water, dust, dirt, and/other potentially damaging materials. Some cases can include an attachment region that is configured to receive an auxiliary component to be used and/or attached with the mobile electronic device, such as an auxiliary lens or other optical device that can be used and/or attached with an onboard camera of the mobile electronic device.

Abstract: Some embodiments disclosed herein relate to an optical system having multiple (e.g., two or more) optical components attached to a retainer portion, and the retainer portion may be removably attached to mobile electronic devices such as mobile phones, tablet computers, media players, and the like. In some embodiments, the optical components may be permanently or removably attached to the same face of the retainer portion. The optical system may be oriented in at least two different positions with respect to a mobile electronic device. In a first position, a first optical component may be generally aligned with an onboard camera of the mobile electronic device, and in a second potion a second optical component may be aligned with the onboard camera.
