Abstract
A detector cell, having a capillary entrance elbow through which a beam of exposing light can be directed into the bore of a central leg of the detector cell capillary. Ray traces, to determine the effect of the entrance elbow on the beam of exposing light are used to optimize performance of this detector cell. Back ray tracing is implemented to illustrate an optimized embodiment. Forward ray tracing is also illustrated and can be used to determine system performance for a range or choices of a single parameter or for concurrent ranges of choices of a subset of the parameters of the beam of exposing light.
