The present technology provides for a fluorescent detector that is configured to detect light emitted for a probe characteristic of a polynucleotide. The polynucleotide is undergoing amplification in a microfluidic channel with which the detector is in optical communication. The detector is configured to detect minute quantities of polynucleotide, such as would be contained in a microfluidic volume. The detector can also be multiplexed to permit multiple concurrent measurements on multiple polynucleotides concurrently.
