Abstract

An optical imaging device, particularly an objective, is provided with at least one optical element, which is mounted in an inner ring, the inner ring being connected to an outer mount. A manipulator device serves for the displacement of the optical element in at least one direction that is perpendicular to the optical axis. By a system of peripheral slots between the inner ring and the outer mount with connecting members situated therebetween, a rotary joint between the inner ring and the outer mount, and at least one displacing rotary joint with an adjusting member between the inner ring and the outer mount as the manipulator device, a displacement of the optical element is attained with low deformation or controlled deformation of the optical element. The inner ring and the outer mount are preferably constituted monolithically.

Dependent claims

An optical imaging device comprising:

an outer mount,
an inner ring connected to said outer mount,
at least one optical element mounted in said inner ring,
a manipulator device comprising at least one adjusting rotary joint or hinge (8, 9, 10) with an adjusting member (11a, 11b) between said inner ring (3) and said outer mount (1) for path-controlled displacement of said optical element in at least one direction that is perpendicular to the optical axis of the imaging device or which is situated at an optionally selected angle to said optical axis,
a system of peripheral slots (4) between said inner ring (3) and said outer mount (1) with connecting members (5) situated therebetween, and
a rotary joint or hinge (6) between said inner ring (3) and said outer mount (1),
whereby displacement of said optical element (2) is attained with low deformation or controlled deformation of said optical element (2).
