Abstract
An optical device and a method of making an optical device are disclosed. A printed wiring board is formed that includes coupling elements at selected locations. The coupling elements are formed using a printed wiring board manufacturing technique. A light source may be coupled to the printed wiring board at one of the coupling elements. An optical structure for directing light from the light source may be coupled to the printed wiring board at another coupling element. A tolerance for a distance between the optical structure and the light source is thus controlled using the manufacturing technique.
Claims14
A method of making an optical device, comprising:
- forming coupling elements at selected locations on a printed wiring board using a printed wiring board manufacturing technique;
- coupling a light source to the printed wiring board at one of the coupling elements;
- and
- coupling an optical structure to the printed wiring board at another of the coupling elements at a selected distance to the light source, wherein a tolerance for the selected distance is controlled using the printed wiring board manufacturing technique.
An optical device, comprising:
- a printed wiring board having a first coupling element and a second coupling element formed thereon using a printed wiring board manufacture technique;
- a light source coupled to the printed wiring board at the first coupling element;
- and
- an optical structure coupled to the printed wiring board at the second coupling element, wherein a tolerance of a distance between the optical structure and the light source is controlled via the manufacturing technique.
