Abstract
An optically aligned optical component assembly. Each optical component has a plurality of first fastening studs. The surface of a support is provided with second fastening studs, where the second studs are formed with parts made of a material that can be soldered to the studs. The optical components are assembled onto the support using corresponding parts. The volume of each part is determined so that the components are optically aligned along a direction that is perpendicular to the surface of the support. This is especially used in the field of microelectronics.
Claims10
An optical apparatus, comprising:
- a support comprising support fastening studs;
- optical components each having an optical axis and each comprising component fastening studs;
- and
- bumps comprising a meltable material, each of said bumps being provided between one of said support fastening studs and one of said component fastening studs, wherein:
- said bumps have a height so that the optical axes of the optical components are aligned with each other along a direction perpendicular to a surface of said support, the height of each of said bumps being dependent on the size of a support fastening stud fastened to said each of said bumps,
- said support fastening studs and said component fastening studs are wettable by said meltable material,
- said support comprises areas surrounding said support fastening studs and not wettable by said meltable material, and
- said optical components comprise areas surrounding said component fastening studs and not wettable by said meltable material.
A process for assembling optical components on a support, each of said optical components having an optical axis, comprising:
- forming component fastening studs on each of said optical components;
- forming support fastening studs on a surface of the support;
- forming parts with a meltable material on said support fastening studs and having a height depending on the size of said support fastening studs;
- positioning said optical component so that said component fastening studs are positioned on said parts;
- and
- melting said meltable material, thereby fastening said optical components to said support so that the optical axes of the optical components are aligned with each other along a direction that is perpendicular to the surface of the support.
