ABSTRACT:
A sample cell assembly employs optics for focusing light though a sample cell, such as one used in electrophoresis. The optical array includes a first cylindrical lens having a central longitudinal axis in a common plane with the longitudinal axis of the sample cell. A second cylindrical lens has its central longitudinal axis oriented transversely to this common plane on another side of the sample cell from the first cylindrical lens. Preferably, a fiber optic beam splitter has a plurality of strands terminating in parallel second ends in the common plane so as to pass light at different longitudinally spaced locations through the sample cell cavity. Here, a plurality of second lenses receive the different light components to focus them respectively on different photodetectors each to create a sample data signal. Where a plurality of sample data signals are generated, processing electronics superimpose them to obtain an augmented signal of aggregate data. The invention further includes a method of measuring optical absorbance utilizing this technique and apparatus.
