The device incudes an attachment body wherein the proximal side of the attachment body is attached to a mobile device via a magnetic array that may be positioned in at least two different positions. The distal side of the attachment device includes an array of magnets to connect with the lens of a medical device. In one or more of the magnetic arrays at least one pair of axially magnetized magnets are positioned in antiparallel arrangement relative to each other to reduce the expanse of a magnetic field while at the same time increasing the magnetic field strength close to the magnetic poles. ## Claims ### Claim 1 An attachment apparatus for optically coupling a mobile device camera to a lens of a medical examination device, said apparatus comprising: an attachment body, said attachment body comprising: a proximal side for attaching to a mobile device, said proximal side comprising a first array of magnets, said first array of magnets being releasably detachable from the attachment body and reversibly positionable on the body to a first position and a second position;
