Abstract

394,285. Optical instruments. ZEISS, C., [Firm of], Carl-Zeiss-Strasse, Jena, Germany. Feb. 23, 1933, No. 5501. Convention date, Feb. 25, 1932. [Class 97 (i).] In an optical observation-instrument having an ocular for viewing an image produced in an image plane, a supplementary device is provided for removing entoptic disturbances due to small exit pupils, such device comprising optical means so disposed in the path of the imaging rays that the rays issuing from the instrument cover a surface which is larger than the exit pupil. In Fig. 2, 0<2> is an ocular for viewing an image P. The supplementary device, which is placed behind the ocular, comprises an inclined plane-parallel glass plate a rotatable about the axis b-b of the instrument, this plate producing a displacement c of the exit pupil p and consequent increase in the area covered by the emergent rays. An increased area is also obtainable by using a stationary plate covering only half the exit pupil. The plate may be replaced by a rhomb having two parallel reflecting surfaces, or by a doubly-refracting prism. The emergent rays may be received by a telescope which can be adjusted to enable the image to be viewed by an ametropic eye. In Fig. 7, the supplementary device comprises a rotatable refracting prism n placed in front of the ocular 0<2>. This produces a displacement q of the exit pupil and also an alteration in the direction of the emergent rays. The prism may be replaced by a glass disc having a frosted surface producing the same effect as a large number of small prisms. The device shown in Fig. 9 consists of a converging lens s disposed in front of the ocular in such a position that its principal plane H<1> contains the image point P so that this point is imaged in the other principal plane H<2>. Movement of the lens at right-angles to the axis b-b produces a change in the direction of the emergent rays and hence a displacement of the exit pupil. Fig. 10 shows a construction embodying the form shown in Fig. 9, the supplementary device comprising a number of lenses s circularly arranged on a rotary disc u and having common principal planes. The disc extends through a slot in the instrument tube x. The eye-piece mount y can be adjusted axially for focusing.
