Device.

2. The device of Claim 1 , wherein the housing comprises a light seal.

The one or more engagement features are configured to orient the received portion of the fluid conduit by mating with alignment features of the received portion of the fluid conduit. A device according to claim 1 .

2. The device of claim 1 , wherein the one or more engagement features comprise open slots.

2. The apparatus of Claim 1 , wherein the at least one illumination source comprises a plurality of illumination sources.

6. The apparatus of claim 5 , wherein the illumination source is configured to illuminate in a first illumination direction and a second illumination direction orthogonal to the first illumination direction.

6. The apparatus of Claim 5 , wherein at least two of said illumination sources are configured to illuminate along a first plane at a first wavelength.

6. The apparatus of Claim 5 , wherein at least another two of said illumination sources are configured to illuminate along a second plane substantially parallel to said first plane.

2. The apparatus of Claim 1 , wherein the illumination source comprises a first illumination source configured to emit light at a first wavelength between approximately 800 nm and approximately 900 nm.

2. The apparatus of Claim 1 , wherein the illumination source comprises a second illumination source configured to emit light at a second wavelength between about 400nm and about 450nm.

2. The apparatus of Claim 1 , wherein the illumination source comprises a fourth illumination source configured to emit light at a third wavelength between approximately 230 nm and approximately 290 nm.
