Abstract
A method for manufacturing an objective. A component at risk of icing up, for example an optical lens or a radiation-permeable cover, is inserted into a housing and connected to, preferably braced against, the housing, by an interconnection of a heating ring made of an electrically conductive elastomer material. An objective, and an imager module that includes an objective are also description.
Claims24
A method for manufacturing an objective, the method comprising:
- inserting a component at risk of icing up into a housing, and connecting the component at risk of icing up to the housing by an interconnection of a heating ring made of an electrically conductive elastomer material;
- wherein:
- (a) a radial extension of the component at an axially central region of the component is less than respective radial extensions of the component at each of first and second axial points of the component axially surrounding the axially central region;
- and
- (b) the heating ring (i) includes an exterior circumferential surface that has a radial protrusion that protrudes exteriorly from a recessed section of the exterior circumferential surface and (ii) is arranged around the component so that the protrusion is in the axially central region and the recessed section is at least partly in one of the first and second axial points so that, after the inserting, the radial protrusion causes the heating ring to press radially inward against the component in the axially central region.

An objective, comprising:
- a housing;
- and
- a component at risk of icing up which is inserted into the housing and connected to the housing by an interconnection of a heating ring made of an electrically conductive elastomer material;
- wherein
- (a) a radial extension of the component at an axially central region of the component is less than respective radial extensions of the component at each of first and second axial points of the component axially surrounding the axially central region;
- and
- the heating ring (i) includes an exterior circumferential surface that has a radial protrusion that protrudes exteriorly from a recessed section of the exterior circumferential surface and (ii) is arranged around the component so that the protrusion is in the axially central region and the recessed section is at least partly in one of the first and second axial points so that the heating ring is pressed, by the radial protrusion, radially inward against the component in the axially central region.

An imager module, comprising:
- an objective, including:
- a housing, and
- a component at risk of icing up which is inserted into the housing and connected to the housing by an interconnection of a heating ring made of an electrically conductive elastomer material;
- wherein:
- the imager module is a camera or sensor;
- a radial extension of the component at an axially central region of the component is less than respective radial extensions of the component at each of first and second axial points of the component axially surrounding the axially central region;
- and
- the heating ring (i) includes an exterior circumferential surface that has a radial protrusion that protrudes exteriorly from a recessed section of the exterior circumferential surface and (ii) is arranged around the component so that the protrusion is in the axially central region and the recessed section is at least partly in one of the first and second axial points so that the heating ring is pressed, by the radial protrusion, radially inward against the component in the axially central region.
