Abstract
An optical discrimination apparatus adapted for use in PCR testing and the like. The apparatus includes a multi-color light emitter to emit excitation light, a sample holder configured to hold dye-marked nucleic acid fragments in a PCR solution at a position configured to receive the excitation light along a first direction, light emission collection optics configured to collect scattered excitation light and light emission (fluorescent emission) from the sample holder along a second direction that is approximately orthogonal to the first direction, a spectrally-dispersive element configured to spectrally disperse scattered light and emission light, and a spectral detector configured to receive the separated emission light and excitation light on different photosites of the spectral detector. Systems and methods are provided, as are other aspects.
