Portable device for detecting molecule(s)

摘要: An optical assembly 140 for a portable device detecting molecule(s) within reaction vessels 110 comprises collimator 403, beam splitter arrangement and plurality of guide arrangements 143. The 403 collimates an excitation from source 400. splits the into split beams. Each incoming two In case where more than one splitter, splitters are arranged in tiers such that first tier receiving collimator, each other or splitters. at least receives previous tier. guides respective beams along path A vessel containing sample to stimulate emission light sample. further detection B towards detector 142.
