Product Family Description

  • Common Wavelengths for Popular Fluorophores
  • >93% Transmission
  • >OD 6 Blocking, <3% from Edge of Bandwidth

Our TECHSPEC® Fluorescence Bandpass Filters are perfectly matched to common fluorophores used in fluorescence imaging applications. Featuring >93% transmission and >OD 6 blocking outside of the passband, these filters are also ideal components in spectroscopy and clinical chemistry applications and biotech instrumentation. Each filter is hard sputtered coated on a single fused silica substrate, and mounted in a black anodized ring.
