Mountable, afocal adaptor for a camera

A mountable afocal adaptor for a camera having a rotation mechanism comprising a rotation ring and a wave spring clamp, wherein the rotation ring is affixed to an attachment plate affixed to the front of a camera housing of a camera and the wave spring clamp affixed to an afocal optical module, wherein the rotation ring and wave spring clamp are mounted relative to each other to rotate around a rotational axis aligned with an axis of an optical path formed between the afocal optical module and the attachment plate and aligned with a view axis of the camera, wherein the rotation mechanism permits rotation of the camera housing around the rotational axis relative to the afocal optical module, and wherein the wave spring clamp is configured with an interlock surface and the rotation ring is configured with an interlock engagement surface that engages with the interlock surface to lock an orientation of the rotation ring.

A method for providing a mountable afocal adaptor for a camera, comprising:

• recording an optical image received by an afocal optical module, the optical image recorded in a first orientation when a camera housing is rotated into a first position, the afocal optical module having a rotation mechanism comprising a rotation ring and a wave spring clamp, wherein the rotation ring is affixed to an attachment plate affixed to the front of the camera housing of a camera and the wave spring clamp affixed to an afocal optical module, wherein the rotation ring and wave spring clamp are mounted relative to each other to rotate around a rotational axis aligned with an axis of an optical path formed between the afocal optical module and the attachment plate and aligned with a view axis of the camera, wherein the rotation mechanism permits rotation of the camera housing around the rotational axis relative to the afocal optical module, and wherein the wave spring clamp is configured with an interlock surface and the rotation ring is configured with an interlock engagement surface that engages with the interlock surface to lock an orientation of the rotation ring;
• and
• recording an optical image in a second orientation when the camera housing is rotated into a second position.
