<p>The set of inventions relates to the engineering of optical instrument-making, in particular to guidance systems. The inventive guidance principle consists in displacing the eyes with respect to the guidance system in order to choose an optimal vision of a shape and/or geometry and/or the distribution of brightness amongst the parts of the inventive aiming mark. The inventive device for guidance system is embodied in such a way that it makes it possible to automatically change the optical magnification with respect with the change of a distance between the centre of the field of view and an object. The device of the carrier of visualised information is provided with an orifice arranged near a crystal and lighted without cells. In another embodiment, said device is provided with a reflecting and/or dispersing element arranged in the direction of the radiation of the crystal. An adjusting device is provided with an elastic element which is compressed in order to bring a deforming element of the device to the neutral position. When an element of the visual part is being produced, an optical component is introduced into the mould as a reinforcement.</p> |
