Image stabilizing instrument
First Claim
Patent Images
1. An image stabilizing optical instrument, comprising:
- a housing (9;
43);
a cardanic part (11;
49) connected to the housing via a suspension for rotary motion about a first pivot axis (12;
50); and
an objective lens system (2;
37), a first optical element (3;
38) including a reflecting surface, and a second optical element (4;
40) including at least one reflecting surface, along a light path, wherein at least some part of the objective lens system (2;
37) and the first optical element (3;
38) are fastened together to constitute a unit (22;
58) that is connected to the cardanic part (11;
49) via suspension for rotary motion about a second pivot axis (25;
44), the second optical element (4;
40) being fastened to the cardanic part (11;
49);
the objective lens system having an unstabilized part (106) and a stabilized part, wherein the unstabilized part (106) has a difference in focal length between two wavelengths to at least partly compensate for chromatic aberration caused by refraction in the instrument when said stabilized part of the instrument is decentered.

Abstract
An image stabilizing instrument, for example for a binocular, in which synchronous image stability is achieved by fastening two objectives (2, 2'"'"') and two attached first reflecting optical elements (3, 3'"'"') to a stabilized frame (22), uni-axially pivoted in a cardanic part (11). Second optical elements (4, 4'"'"') in each of two parts of the binocular are fastened to the cardanic part (11), which in turn is uni-axially pivoted in the binocular housing (9). The front window fastened to the housing is designed as a color-correcting lens (106) to correct for color aberration.
