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.
