摘要： A zoom lens in which two pairs of optical elements of the lens are each movable simultaneously relative to each other to attain desired magnification while maintaining the image surface of the lens system substantially fixed.A common body supporting both sets of lens elements can be moved if required to maintain the focal plane of the lens system fixed. The need for moving the body may arise where the movement of the lens elements causes a shift or displacement of the focal plane of the zoom lens.

摘要： A variable power copying lens system having an intermediate range of variable magnification with superior distortion aberration compensation and compact size. The lens system includes, in order from the object side, a first lens group having a negative focal length, a second lens group having a positive focal length and a third lens group having a negative focal length. The distance between the first and second lens groups and the distance between the second and third lens groups is variable simultaneously with variation of the overall lens system position to thereby maintain the distance between the object surface and image surface constant.

摘要： A camera of the so-called pocket type having an objective lens including means for varying the equivalent focal length. The optical axis of the overall lens is folded to have two forward portions and a connecting lateral portion with the primary zooming elements on the lateral portion. The view finder system axis is a linear continuation of the lateral objective axis.

摘要： A mount and mechanism for a symmetrical zoom lens in which the outer lens elements are stationary relative to the lens housing. The inner elements on one side of the center move in unison on one shaft driven in symmetrically opposite direction relative to another shaft on which the inner lens elements on the other side of the lens center move.The entire zoom lens housing is mounted for sliding movement, between object and image, on a carriage which is in turn mounted for movement along a stationary frame. The frame includes an iris cam which is in engagement with an iris cam follower which in turn is connected by a linkage to the lens iris to control the lens aperture in response to the axial position along the carriage of the lens housing. The maximum opening of the lens iris is at the highest magnification and the minimum opening of the lens aperture is at the lower magnification.

摘要： An improved photographic still pocket camera, where the film is inserted in a cassette provided with a feed part or spool and a take-up part or spool, these parts or spools connected by a film guide ledge. A zoom lens is mounted inside the camera, with the picture-taking beam path of the zoom lens located essentially parallel to the film plane and hence transverse to the direction of picture taking. The movable lens elements of the zoom lens are also movable parallel to the film plane.

摘要： A folded optical system for scanning an object and projecting its image in four modes of operation. In one mode, a stationary object is scanned by moving mirrors and its conjugate image projected at unity magnification onto a moving image surface. In a second mode, conjugate distances are varied to project an image at other than unity magnification. In a third mode, the optical system remains stationary and the object is moved relative to it to enable imaging of objects larger than the scan travel of the optics. In a fourth mode, the optics again remain stationary and an add-reflector is introduced to create a reflection cavity to increase the object conjugate for minified imaging of large moving objects. Mirrors and lens are movable to effect magnification changes.
