Abstract: This specification describes a reflex camera with an off-axis viewer having a novel aperture stop to provide the viewer with a stigmatic exit pupil. One embodiment of the aperture stop has its horizontal edges separated from its vertical edges by forming them as orthogonal slots in different surfaces spaced along an optical path joining the camera and the viewer.

Abstract: An improvement for a ruling engine enables the ruling engine to generate master dies for molding Fresnel optics with a cylindrical or a toroidal power component together with a spherical power component and thereby implement a method for generating anamorphic Fresnel optical elements. The improvement includes a device to change the pitch of the ruling engine''s cutting tool as a function of its azimuth on a work piece revolving beneath it.

Abstract: This invention is an improved landscape lens for a simple photographic camera. The improvement is achieved by placing a vignetting stop midway between the lens element and its regular aperture stop. It reduces the amount of blur otherwise found in the image at points removed from the center of the field. An aspheric refracting surface on the lens element further improves the image.

Abstract: The invention is an optical element, one version of which is useful for operating an automatic exposure control of a selfcontained camera coupled to a microscope without detracting from the brightness of the magnified image to be recorded on the camera''s film format. The article includes three reflecting surfaces arranged to extract a small part of the light emerging from the microscope''s eyepiece and direct it into the photodetector of the automatic exposure control. A lens refracts the light, after the third reflection, to improve the distribution of the light onto the camera''s photodetector. The article is suitable for manufacture as a homogeneous molding of transparent plastic.

Abstract: A reflex camera having an aberration reducing image reflection surface for use in viewing an image, transmitted through an entrance pupil to the image reflection surface, at an exit pupil remote from both the reflection surface and the entrance pupil. The reflective surface is generally planar and so formed as to provide a plurality of ellipsoidal segments extending thereover. The ellipsoidal segments are provided with common foci, whereby any light passing through the entrance pupil and impinging on any of the ellipsoidal segments will be reflected to the exit pupil.

Abstract: A method and apparatus is provided for fabricating novel imaging apparatus. The subject invention accomplishes its purpose by employing a stylus which is driven into a base to produce a facet therein which is normal to the longitudinal axis of the stylus. he stylus is secured in predetermined relation with respect to a pair of points and is caused to traverse the surface of said base until a desired portion thereof is sufficiently covered with said facets. One of said pair of predetermined points corresponds to a point source of illumination or other electromagnetic radiation and the other of said pair of predetermined points corresponds to a point to which it is desired to reflect any electromagnetic radiation incident on said faceted base from said point source.
