Abstract: A detector for use in optical measuring instruments such as a double-beam spectrophotometer, comprising a photoelectric element having a photosensitive surface and a beam mixer disposed adjacent the photosensitive surface for causing each of two alternate light beams to be projected evenly and uniformly onto the photosensitive surface of the photoelectric element thereby to eliminate errors which would otherwise be caused in the result of measurement due to local difference in sensitivity of the photosensitive surface of the photoelectric element. The beam mixer comprises a symmetrical pair of light diffusing plates so arranged as to form a roof-shaped configuration and a tublar body having one end opening closed by the pair of light diffusing plates and the opposite end opening closed by the photosensitive surface of the photoelectric element.

Abstract: This specification discloses an apparatus disposed in the light beam from an object passed through an imaging lens for producing an output variable with movement of the image of the object by the imaging lens in the direction of the optical axis. The apparatus produces, when the image of the object is formed on a predetermined imaging plane, an output corresponding to a critical value representative of the in-focus of the imaging lens to the object and produces, when the image of the object is formed at a position deviated from the predetermined imaging plane, an output corresponding to the amount of said deviation. The apparatus includes detector means disposed at a position biased in the direction of the optical axis from the predetermined imaging plane so as to produce an output corresponding to the critical value when the image of the object is formed on a plane biased by a predetermined amount in the direction of the optical axis from the predetermined imaging plane and to produce an output corresponding to the predetermined amount of bias when the image of the object is formed on the predetermined imaging plane, memory means in which a data representative of the predetermined amount of bias is prerecorded, and means for correcting the output of the detector means on the basis of the prerecorded data.

Abstract: An apparatus for electrooptically focusing the objective in a single lens reflex camera provided with a focusing screen and a split image wedge rangefinder, where focus detectors are used in which an image segment is scanned in an image plane. The focusing window of the focusing screen provided with a split image wedge rangefinder (5) is followed by a pentaprism (8) having a first plane reflecting surface which is partly reflecting. The scanning grating (14) and the photoelectric detector system (17,18) are mounted in the direction of the light beam behind this plane surface of the pentaprism and along the optical axis deflected by one of the wedges (5a) and an optics (11) is present along the optical axis to image the plane of one of the wedges (5a) into that plane where the scanning takes place.

Abstract: Behind an objective which is axially movable, is provided a beam splitter to divide the light path passing through the objective into two light paths. In one of the light paths on the image plane of the objective is located a prism. Behind the prism is provided a photodetector in the optical path includng the prism. In the optical path which does not have the prism also is provided a photodetector at a position which is optically conjugate with the other photodetector. The output of the photodetectors are connected to an output comparing circuit which is connected to a servomotor for controlling the position of the objective. When the outputs of the two photodetectors are equal to each other, the servomotor is stopped.

Abstract: An apparatus is described for reading a record carrier with an optical information structure, in which apparatus errors in the focussing of a read beam on the information plane are detected with an astigmatic focussing-error detection system.By including a beam splitter in the path of a beam which has been reflected by the record carrier and by including an astigmatic focussing-error detection system in each of the paths of the two sub-beams thus obtained, the astigmatism of the one detection system being opposed to that of the other detection system, a focussing-error signal can be derived which is independent of optical faults in the read apparatus.
