Patent attributes
Some embodiments disclosed herein relate to an optical device with one or more optical components (e.g., lenses) attached to a retainer portion or clip. The optical device can be removably attached to mobile electronic devices, such as mobile phones, tablet computers, media players, and the like. The retainer portion may be configured so as not to interfere with a user's view of a display panel of the mobile device. The optical device may include one or more energy conveying paths to allow energy to be conveyed to and/or from various components of the mobile device, such as flashes or microphones. In some embodiments, additional features may be provided, such as optical components tilted to complement a tilt of an onboard camera of a mobile device, and structures or adapters to reduce friction or allow an optical device to be attached to mobile devices of varying thicknesses.
