Patent ID: 7349603

Claim:
An optical arrangement comprising: two parallel plates each having a through-hole defining an optical input/output defining an optical axis; an at least partly optical component between the plates, the at least partly optical component and a first plate of the two parallel plates comprising first fastening studs positioned transversely opposite on the first plate and on the at least partly optical component and connected by first bumps comprising a meltable material that when molten are configured to selectively wet the first fastening studs to optically align the at least partly optical component and the optical input/output of the first plate, wherein the two parallel plates further comprise second fastening studs positioned transversely opposite on the two parallel plates and connected by second bumps comprising a meltable material, and wherein the second fastening studs are distinct from the first fastening studs and are configured to limit lateral movement of the second bumps, such that when molten, the second bumps selectively wet the second fastening studs to optically align the optical input/output in each of the two parallel plates.
