Abstract: An optical system includes an optical device which is a spherical body or has a spherical shape and includes a first spherical surface, a plurality of two-by-two adjacent blocks covering the first spherical surface, and at least one light-transparent filler substance contained in a spherical cavity of the optical device. The optical system includes a curved focal plane surrounding the optical device and on which an image produced by the latter is focused, and a receiving device having a plurality of chambers arranged at the curved focal plane. Each chamber includes a field lens and a diaphragm arranged downstream of the field lens with respect to the center of the optical device. The diaphragm has the center on the optical axis of the field lens so that optical projection of the diaphragm onto the optical device through the field lens defines a virtual diaphragm extending into the optical device.

Abstract: Telescope with optical resolution and continuity of the field of view comprising a spherical primary mirror, wherein: a) said telescope is equipped with a field of view and a system of repartitioning the field of view, b) said system of repartitioning the field of view is placed in proximity of die focus of the primary mirror, and is constituted by a secondary mirror composed of n planar reflective surfaces, c) said n planar reflective surfaces are contiguous sine to the other and form a continuous multifaceted prismatic reflector, so as to obtain continuity of the field of view over the whole field, d) said n planar reflective surfaces are followed by a corresponding number of optical cameras that form n portions of image in n distinct focal planes, and e) a collecting and recording element is positioned on each n-th focal plane.

Abstract: Telescope with wide Field of View, high optical resolution and continuity of the field of view comprising a spherical primary mirror, wherein a) said telescope is equipped with a system of repartitioning of the Field of View, b) that said system of repartitioning of the Field of View is placed in proximity of the focus of the primary mirror, and is constituted by a secondary mirror composed by n planar reflective surfaces, c) said n planar reflective surfaces are contiguous one to the other and form a continuous multifaceted prismatic reflector, in such a way as to obtain the continuity of the field of view over the whole field, d) said n planar reflective surfaces are followed by a corresponding number of optical cameras that form n portions of immage in n distinct focal planes, e) a collecting and recording element is positioned on each n-th focal plane
