Abstract
A method for aligning optical components includes positioning a flexure having an attached first optical component with respect to a substrate having a second optical component attached thereto. The flexure has at least two legs, and each leg has a foot portion. The method further includes coupling at least one leg of the two legs to the substrate at a point of contact between the foot portion of the at least one leg and the substrate. The method further includes adjusting the alignment of the optical components by spot welding a location on the leg. Spot welding on the substrate may also be used to adjust the alignment of the optical components.

A method for aligning optical components, the method comprising:
- positioning a flexure having an attached first optical component with respect to a substrate having a second optical component attached thereto, the flexure having at least two legs, each leg having a foot portion;
- coupling at least one leg of the two legs to the substrate at a point of contact between the foot portion of the at least one leg and the substrate;
- and
- adjusting the alignment of the optical components by spot welding at least one location on the leg.
A method for aligning optical components, the method comprising:
- positioning a flexure having an attached first optical component with respect to a substrate with a second optical component attached thereto, the flexure having at least two legs;
- moving the flexure until optical axes of the first and second optical components are aligned;
- coupling a first plurality of legs at a first end of the flexure to the substrate by spot welding at least one location on each leg of the first plurality of legs at the first end of the flexure;
- moving the flexure to adjust the optical alignment between the first and second optical components;
- and
- coupling a second plurality of legs at a second end of the flexure to the substrate.
A method for realigning optical components, the method comprising:
- providing a flexure having an attached first optical component, the flexure having a body and at least two legs extending from opposite sides of the body, each leg having a foot portion, the flexure being mounted on a substrate, wherein the foot portion of each leg is spot welded to the substrate;
- and
- realigning the first optical component with a second optical component by spot welding at a selected location on a line of contact between the flexure and the substrate.
