Abstract:
1. Optical apparatus, comprising: a spectacle frame, which is configured to be worn by a user and comprises a bridge piece and temples; and a telescope, which is fixed to the spectacle frame and which comprises an objective adjacent to a temple of the frame, an eyepiece, and multiple optical surfaces defining a folded optical path for providing a magnified image to an eye of the user while at least one of the optical surfaces is a reflective surface adjacent to the temple, which is located on the optical path between the objective and the eyepiece and at least partially posterior to a coronal plane located at a rear surface of the eyepiece, such that the optical path enters the telescope by passing through the coronal plane in a posterior direction, and is then reflected by the reflective surface to pass back through the coronal plane in an anterior direction, and thereafter passes through the rear surface of the eyepiece in the posterior direction.
