    Abstract: The device for correcting the color of a color film printing machine, equipped with three different optical filters which divide the diaphragm hole of an optical system condenser on three segments and two leaves, which partially stop down the filters; at the same time the leaves are suitably equipped with curved guides and pivot around points. Every pair of leaves is driven by a common lever equipped with a slide, which at the lever pivotal point, moves along guides. The linear increases of the lever turning angle is accompanied with a logarithmic increase of the filter-active field, for example, with a suitable radius of curvature, the guides, the length of lever, coordinates of the leaves', pivot points of lever, coordinates of pivot points of leaves, of the distance between the edge and the point of the leaves' pivot point, and coordinates which define the position of the guide curvature center in relation to the leaf edges.

    Abstract: 1435134 Holography CENTRALNE LABORATORIUM OPTYKI 14 May 1973 [20 May 1972] 22808/73 Heading G2J In a holographic microscope the laser light is "averaged" before passing to the beam-splitter. The "averaging" which suppresses optical noise is obtained in a confocal assembly of two lenses and a slit arranged at the common focus of the lenses and a deflecting element arranged continually to vary the direction of deflection of the high beam passing through and being situated between one of the lenses and the focal plane. The element may physically rotate about an axis perpendicular to the axis of the light beam (mirror or prism) or may functionally rotate (electro-optic or electroacoustic element).

    Abstract: 1287025 Optical apparatus CENTRALNE LABORATORIUM OPTYKI 22 April 1970 [2 May 1969] 19174/70 Heading G2J [Also in Division G1] A photometer arrangement enabling simultaneous observation of an object and of the diaphragm D, limiting the area being photo-metrically determined comprises means defining a main light path, polarizing beam-splitting means P, dividing the main path into an observation path and a measuring path carrying light beams mutually orthagonally polarized, the eye-piece S 5 being disposed in the observation path, and aperture D, being disposed in the measuring path, specular reflector means being disposed in at least one of the paths, and two phase retarders, are in each of the measurement and observation path, the arrangement being such that the observation image and the aperture image are mutually orthagonally polarized. As shown, the aperture is formed in a mirror, and filter F is provided prior to photo-electric cell K. In an alternative embodiment Fig.2 (not shown), the aperture is not reflecting, but a second beam-splitter is provided behind the aperture, together with a lamp for illuminating the aperture. Polarizer P1 is provided in the eye-piece so that, by rotation, either of the mutually orthagonally polarized images may be varied in intensity.
