Fluorescence-based assays depend on detecting photons. Common to such assays is the notion of the ‘good’ photon, which carries useful assay information, and the ‘bad’ photon, which carries noise, background, or other information that imperils the assay. A robust assay can succeed despite some level of these ‘bad’ photons, but a more sensitive or difficult one might need a much higher ratio of ‘good’ to ‘bad’ photons to ensure success.

Spectral flow cytometry requires filters covering the UV, visible, and NIR in discrete steps, which may lead to a desire to balance instrument cost and optical filter performance. IDEX Health & Science understands these needs, and we are proud to announce our latest Semrock bandpass optical filters: Nanopede™. These essential performance and cost-effective filters cover the near UV and visible spectrum in even (Flight 1) and odd (Flight 2) 20 nm Full-Width, Half-Max (FWHM) steps.
