An angled mirror for an armored vehicle includes a housing having a lower look-in window or aperture, an upper look-out window or aperture and a one-part or multipart prism located in the housing. The prism has an outside view surface which remains permanently functional in strongly sandy surroundings due to a layer made of transparent ceramic that is disposed in the look-out window or aperture.

A camera module includes an imaging lens system, an image sensor and a plurality of light-folding elements. The imaging lens system is configured to focus imaging light onto an image surface. The image sensor is disposed on the image surface. The plurality of light-folding elements includes at least one image-side light-folding element disposed on an image side of the imaging lens system, and each of the light-folding elements is configured to fold the imaging light from an entrance optical path thereof to an exit optical path thereof. At least one light-shielding mechanism is arranged on at least one of the entrance light path and the exit light path of the at least one image-side light-folding element. The at least one light-shielding mechanism has a minimal opening, and the minimal opening surrounds the imaging light in the at least one of the entrance optical path and the exit optical path.

A head for a walk-around costume is provided that is adapted for enhanced visibility. The costume head includes an outer shell defining an interior space for receiving a head of a human performer. The outer shell includes an aperture allowing incoming light from an exterior space to enter the interior space, and an eye location for the human performer is spaced apart from the aperture when the head is received in the interior space. To provide an enlarged field of view, the costume head includes an optical viewfinder assembly disposed within the interior space of the outer shell between the aperture and the eye location. The optical viewfinder assembly is adapted for receiving the incoming light and transmitting the incoming light to the eye location to move a viewpoint of the human performer to the aperture to provide a larger field of view of the exterior space.

An optical element driving device is described that includes a fixed portion having supporting holes, a holding member having a supporting surface formed by a supporting portion supporting an optical element, and a supporting shaft supporting the holding member with respect to the fixed portion in a rockable manner. The supporting shaft has two end portions of cylindrical shape for the supporting holes, and a center portion with first and second outer peripheral surface. The first outer peripheral surface is flush with an outer peripheral surface of the cylindrical shape along an axis line of the cylindrical shape. The second outer peripheral surface is located further inside than the first outer peripheral surface. A center of the first outer peripheral surface is on the supporting surface, and the entire second outer peripheral surface is closer to the first outer peripheral surface than the supporting surface.
