| The invention is directed to an optoelectronic imaging system for industrial applications having at least two optical lenses (1, 2) which are spaced apart from one another and an electronic image sensor (8), wherein the imaging sharpness on the image sensor (8) and the imaging scale (zoom) are mechanically adjustable by means of a control unit. According to the invention, the at least two lenses are constructed as flexible lenses (1) whose surface curvature can be changed in a controlled and reversible manner by application of externally initiated mechanical force (actuating means 15) and are arranged so as to be fixed against displacement relative to one another in the direction of the optical axis, the image sensor (8) is connected by signal links with a data processing device (14) which is, in turn, connected by signal links with the actuating means (15) of the flexible lenses (1) and delivers signals for an autofocussing function, the data processing device (14) has a storage device in which are stored values for the adjustment of the actuating means (15) for changing the focal lengths of the flexible lenses (1) for purposes of the zoom function, and the flexible lenses (1), together with the actuating means (15), image sensor (8) and data processing device (14), form a compact device unit (16). | ||||||

| A zoom lens comprises a plurality of optical elements each of which includes a transparent body having two refracting surfaces and a plurality of reflecting surfaces and is arranged so that a light beam enters the transparent body from one of the two refracting surfaces, repeatedly undergoes reflection, and exits from the other of the two refracting surfaces, and/or a plurality of optical elements on each of which a plurality of reflecting surfaces made from front surface mirrors are integrally formed, and each of which is arranged so that an entering light beam repeatedly undergoes reflection by the plurality of reflecting surfaces and exits from the optical element. In the zoom lens, the optical element which the light beam from an object enters first has an entrance pupil positioned on an object side of a first reflecting surface, and an image of the object is formed via the plurality of optical elements and zooming is performed by causing at least two optical elements from among the plurality of optical elements to vary their relative positions. | ||||||
| 147 | Switching variable magnification finder | US951000 | 1992-09-25 | US5321546A | 1994-06-14 | Hiroshi Takase |
| A switching variable magnification finder includes an objective lens system having a positive refracting power, an image erecting optical system for erecting an image formed by the objective lens system, and an eyepiece system having a positive refracting power, in which an auxiliary lens system is removably disposed behind the objective lens system so that magnification is varied according to the insertion or removal of the auxiliary lens system. Thus, the switching variable magnification finder allows magnification to be changed without increasing the overall of the finder optical system and moving the objective lens system and its switching mechanism to be simplified. | ||||||

| 149 | Optical system utilizing a variable focal length reflector lens | US417786 | 1982-09-13 | US4497617A | 1985-02-05 | Edgar E. Price |
| An optical system utilizes a variable focus half-lens reflector system for projecting images onto an image plane without the use of folding mirrors. The half lens is arranged with its optical axis parallel to the object and image planes. Attached to the entrance face of the lens is a pair of reflectors arranged to form a right angle which is bisected by the lens optical axis. Principal rays from an object are then reflected from the first mirror, reflected again from the back of the half lens, thus passing twice through the lens and then, via a final reflection from the second attached mirror, onto the image plane. | ||||||
| 150 | Macro-focussing rear converter lens | US397806 | 1982-07-13 | US4468107A | 1984-08-28 | Shinji Yabe |
| A macro-focusing rear converter lens system adapted to be inserted between a camera body and a master lens assembly comprises a cylindrical main body which is mounted on the camera body. A rear converter lens assembly for elongating the focal length of the master lens is mounted in fixed relation on the camera body. The master lens assembly is mounted on the front end of a tube which is fitted coaxially within the main body and is movably axially by means of a helicoidal threaded rotatable ring interposed between the main body and the tube on which the master lens assembly is mounted. The interval between the camera body and the master lens assembly can thus be varied by rotating the rotatable ring. A leverage system in the main body transmits an F number signal from the master lens system to the camera body. | ||||||

| A variable focus objective lens having a magnification range in the order of 1 : 30 and greater and having two pairs of relatively movable members which objective consists of a front assembly and a rear assembly which includes one of the two pairs of movable members to which consecutive zooming movement is imparted. This is done in order to add a varifocal range to a varifocal range of zooming movement of the movable members of the front assembly, in association with a control mechanism of simple structure incorporated in barrels of the lens mount therefor. | ||||||

| A compact angle finder with an adjustable magnifying lens system incorporated therein, which is arranged at the rear of an eyepiece of a single-lens reflex camera finder and consists of a Galilean type rotatably adjustable magnifying lens system, an objective lens system including an air space in which is disposed a reflecting member, and an eyepiece lens system, and in which an entrance pupil of said adjustable magnifying lens system substantially coincides with an exit pupil of said eyepiece of the single-lens reflex camera finder, an exit pupil of said adjustable magnifying lens system is located within a range which is about one-half the overall length of said adjustable magnifying lens system from the center of rotation thereof and at the same time said exit pupil coincides with an entrance pupil of a lens system consisting of said objective lens system and said eyepiece lens system.

| 153 | Focusing roll and displacement prisms | US41730873 | 1973-11-19 | US3871750A | 1975-03-18 | MECKLENBORG RICHARD A |
| Optical apparatus comprising two similar prisms, preferably two 30*-60*-90* prisms, with their hypotenuses paralleled for use in providing conjugate compensation and optical axis shift is shown. Movement of either prism along a line which makes a particular angle with the optical axis will change the path length, and movement perpendicular thereto will shift the optical axis. In the case of two 30*-60*-90* prisms, the necessary angle is a 60* angle. By placing a roof on one of the prisms an odd number of reflections is introduced permitting the image to be rolled by rotating the two prisms. The roof also permits optical axis shift in a second direction when the prism is moved in a line perpendicular to the plane bisecting the roof.
