Patent ID: 7514666

Claim:
A composite assembly comprising: a circuit board having a cup-shaped opening formed therein; a first receiver device mounted on the circuit board inside of the cup-shaped opening, the first receiver device operating on a first set of wavelengths of light, the first receiver device having electrical connections that are connected to conductors of the circuit board; a second receiver device mounted on the circuit board, the second receiver device operating on a second set of wavelengths of light, the second receiver device having electrical connections that are connected to conductors of the circuit board; a first filter device disposed at least partially inside of the cup-shaped opening, the first filter device passing light of the first set of wavelengths and filtering out light of other wavelengths such that only light of the first set of wavelengths passes through the first filter device and impinges on the first device; and a second filter device disposed on the assembly, the second filter device passing light of the second set of wavelengths and filtering out light of other wavelengths such that only light of the second set of wavelengths passes through the second filter device and impinges on the second device, and wherein the wavelengths of the first set of wavelengths are different from the wavelengths of the second set of wavelengths.
