OPTICAL MEASUREMENT INSTRUMENT AND METHOD THEREFOR.

摘要

The signal-to-noise ratio (S/N) of optical measurement is improved by adding very small particles absorbing excitation light and/or fluorescence emitted from a fluorescent dye or a water-soluble dye to a reaction vessel (2) formed integrally with a slab type optical waveguide (1) so as to reduce stray light attributed to a reagent.
