    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: An interference system for qualitative and quantitative investigation of micro-objects in transmitted light by means of the variable phase-contrast and variable shear interference methods. The system is located between an microscope objective and eyepiece. It resembles the Michelson interferometer in which a standard light beam splitter is replaced by an interference polarizer (Banning type), giving two orthogonally polarized beams, and two quarter-wave plates inserted in the split beams, and a common linear polarizer placed in the recombined beams. The interferometer mirrors are located in the planes conjugated with an aperture diaphragm of a microscope condenser. For interference investigation a slit condenser diaphragm is used. The optical path difference between the object under investigation and the surrounding medium is measured by the Senarmont method. Image shear is varied by tilting one of the interferometer mirrors. For phase contrast observation a ring-shaped condenser aperture is used together with an annular stop located close to one interferometer mirror and annular opening located close to the other mirror. The annular stop absorbs the direct (undiffracted) light and the annular opening absorbs the diffracted light, thus the first said mirror reflects the diffracted light and the second mirror reflects the direct light. Both light beams are recombined by the interference polarizer and brought to the vibrations in the same polarisation plane by a common linear polarizer. These light beams interfering with each other produce interference images of objects under investigation. The image contrast and contrast sign is changed with the Senarmont compensator.
