Abstract

A method and apparatus for centering an optical component, such as a lens element, within an optical bore sleeve. The optical component has an outer perimeter, and the optical bore sleeve has an inner perimeter for receiving the outer perimeter of the optical component. A plurality of deformable ridges are interposed between the outer perimeter of the optical component and the inner perimeter of the sleeve for aligning the optical component and the sleeve along a common optical axis as the ridges are deformed upon insertion of the optical component into the sleeve.

Claims

1. An apparatus comprising:

a optical component having an outer perimeter; and

an optical bore sleeve having an inner perimeter for receiving the outer perimeter of the optical component;

a plurality of deformable ridges interposed between the outer perimeter of the optical component and the inner perimeter of the sleeve for aligning the optical component and the sleeve along a common optical axis as the ridges are deformed upon insertion of the optical component into the sleeve, wherein the deformable ridges each have a respective longitudinal dimension that is substantially within a range from approximately one millimeter to approximately three millimeters.

2. An apparatus as in claim 1 wherein the deformable ridges extend outwardly from the outer perimeter of the optical component.

3. An apparatus as in claim 1 wherein the deformable ridges extend from the inner perimeter of the sleeve, so as to engage the outer perimeter of the optical component.

4. An apparatus as in claim 1 wherein:

the optical component having the outer perimeter is a lens having an outer perimeter; and

the deformable ridges extend outwardly from the outer perimeter of the lens.

5. An apparatus as in claim 1 wherein:

the optical component having the outer perimeter is a lens having an outer perimeter; and

the deformable ridges extend from the inner perimeter of the sleeve, so as to engage the outer perimeter of the lens.

6. An apparatus as in claim 1 wherein the deformable ridges are substantially uniformly shaped, so as to align the optical component and the sleeve along the common optical axis as the ridges are deformed upon the insertion of the optical component into the sleeve.

7. An apparatus as in claim 1 wherein the deformable ridges are substantially uniformly arranged, so as to align the optical component and the sleeve along the common optical axis as the ridges are deformed upon the insertion of the optical component into the sleeve.

8. An apparatus as in claim 1 wherein the deformable ridges are of a substantially uniform ductility, so as to align the optical component and the sleeve along the common optical axis as the ridges are deformed upon the insertion of the optical component into the sleeve.

9. An apparatus as in claim 1 wherein the deformable ridges each have a respective height dimension that is substantially uniform among the deformable ridges, so as to align the optical component and the sleeve along the common optical axis as the ridges are deformed upon the insertion of the optical component into the sleeve.

10. An apparatus as in claim 1 wherein the deformable ridges each have a respective height dimension that is substantially within a range from approximately one tenth of a millimeter to approximately a half of a millimeter prior to any deformation of the ridges.

11. An apparatus as in claim 1 wherein the deformable ridges each have a respective height dimension that is substantially within a range from approximately five one hundredths of a millimeter to approximately four tenths of a millimeter upon deformation of the ridges as the optical component is inserted into the sleeve.

12. An apparatus as in claim 1 wherein the deformable ridges each have a respective longitudinal dimension that is substantially uniform among the deformable ridges, so as to align the optical component and the sleeve along the common optical axis as the ridges are deformed upon the insertion of the optical component into the sleeve.

13. An apparatus as in claim 1 wherein the optical component has a substantially circular cross section.

14. An apparatus as in claim 1 wherein the sleeve has a substantially circular cross section.

15. A method comprising the steps of:

providing a optical component having an outer perimeter; and

further providing an optical bore sleeve having an inner perimeter for receiving the outer perimeter of the optical component;

interposing a plurality of deformable ridges between the outer perimeter of the optical component and the inner perimeter of the sleeve, wherein the deformable ridges each have a respective longitudinal dimension that is substantially within a range from approximately one millimeter to approximately three millimeters;

inserting the optical component into the sleeve;

deforming the ridges; and

aligning the optical component and the sleeve along a common optical axis.
