Abstract
Attachments for adjusting optical properties of image forming optical systems. An example refocus flip optic adaptor for a night vision goggle may include an adaptor housing for detachably mounting to an objective lens assembly of the night vision goggle and an optical element holder pivotably mounted to the adaptor housing such that a refocus lens (or other optical element) mounted to the optical element holder is selectively positionable in an operative position in which the refocus lens is axially aligned with the objective lens of the night vision goggle and an inoperative position in which the refocus lens and the optical element holder do not affect an image viewable through the night vision goggle. In some example embodiments, the optical element viewing diameter may be substantially the same as objective lens viewing diameter. Example optical elements may affect optical properties such as objective lens focus, optical filtering, and magnification.
