An image-stabilized optical instrument, such as telescopes and cameras, having an objective (1) and first (2) and second (6) optical reflecting elements following in the path of rays after the objective and, wherever applicable, an ocular (9) arranged after said elements, is characterized by the fact that the whole objective, or one or more parts of the latter, depending on the purpose and the optics used, together with the first optical element (2) forms a stabilized unit, which is freely rotatable, in relation to the casing (7) and the second optical element (6) fixed thereto and, wherever applicable, the ocular (9), around two pivot axes which usually intersect. The suspension point (A,B,C) then substantially lies on the imaginary extension (L) of the optical axis of the objective after the first optical element, if the second optical element would not have been in the path of the optical axis.
An image-stabilized optical instrument defining an optical path for the passage of optical rays therethrough, comprising a casing, an objective mounted in said casing in said optical path, a first optical element mounted in said casing in said optical path, said first optical element including at least one plane reflecting surface, a second optical element mounted in said casing in said optical path, said second optical element including at least one plane reflecting surface and being unstabilized and so substantially following the movements of the casing, at least a part of the objective being rigidly connected with the first optical element to form a stabilized unit which is rotatable in relation to the casing around at least one axis.
An image-stabilized binocular type optical instrument defining first and second optical paths for the passage of optical rays therethrough, comprising a casing, a pair of objectives respectively mounted in said casing in said optical paths, a first pair of optical elements respectively mounted in said casing in said optical paths, each including at least one plane reflecting surface, and a second pair of optical elements respectively mounted in said casing in said optical paths, each including at least one plane reflecting surface, said second optical elements being unstabilized and so substantially following the movements of said casing, at least a part of each objective being rigidly connected with one of said first optical elements to form a stabilized unit and said units being rigidly connected to each other and being rotatable through a limited angle in relation to said casing around at least one axis.
