Abstract: A flexure and package including the same are provided. In one embodiment, the flexure is coupled to a second optical element and a substrate to maintain the second optical element in alignment with a first optical element. The flexure comprises a body, a pair of front and back legs. The attachment of the rear legs to the substrate causes the flexure to move from a first flexure position to a second flexure position, the distance between the first flexure position and the second flexure position equaling an offset distance. A specified length of the body is chosen such that the offset distance causes a second offset distance of the second optical component held by the flexure, and this second offset distance is within a specified range. The second offset distance is equal to the difference between a primary second optical component position and a secondary second optical component position.

Abstract: An apparatus for use in calibrating lens position and field of view in an endoscope is disclosed. The apparatus includes tracking elements mounted at fixed positions on the endoscope's shaft, a holder providing an object or pattern to be viewed by the endoscope, when the endoscope is placed in the holder, and positional elements mounted on the holder at known positions. A processor in the apparatus operates to determine the positions of the tracking and positional elements, with the endoscope shaft received in the holder guide, and calculate from the determined positions, the coordinates of the endoscope lens with respect to the tracking elements, and the field of the view of the lens. Also disclosed is a calibration method which employs the apparatus.
