Patent ID: 8351741

Claim:
A system comprising: a plurality of waveguide assemblies, each of said waveguide assemblies comprising: a chamber for accommodating a sample and passing the sample therethrough; a distal end providing at least a first access to the chamber; and a proximal end comprising at least a light transmissive portion; and at least one wall extending from the proximal end to the distal end in a longitudinal direction; and wherein the at least one wall is configured to interact with the sample whereby the wall and the sample comprise a waveguide configuration for directing light emitted by the sample toward the proximal end; and a reservoir for accommodating the sample therein; wherein the sample is delivered from the reservoir into the chamber of the at least one of the waveguide assemblies via the distal end of the least one of the waveguide assemblies, the proximal end comprises a connector, said connector comprising the light transmissive portion, and the light transmissive portion comprises a lens for focusing the light emitted by the sample directed by the waveguide configuration toward the proximal end.
