Product Family Description

Our TECHSPEC® Fluorescence Bandpass Filters are perfectly matched to common fluorophores used in fluorescence imaging applications. Excitation Filters and Emission Filters are available featuring >93% transmission and >OD 6 blocking outside of the passband. These filters are also ideal components in spectroscopy and clinical chemistry applications, as well as biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms. Each filter is hard sputtered coated and mounted in a black anodized ring.

For a complete list of compatible fluorophores for each Excitation or Emission Filter, view Fluorophores and Optical Filters for Fluorescence Microscopy.

All mounted TECHSPEC® Optical Filters have an arrow on the side of the mount that points to the filter-coated surface for quick reference. Filter oriented such that arrow points to filter coated surface S1. Anti-reflective (AR) coating is applied to S2.
