This series of dual-band filter sets feature our high performance ET sputter coatings. Emission filters have two passbands specific for a particular pair of fluorochromes. The sets with dual-band excitation filters allow for simultaneous visualization of two fluorochromes as often required for applications such as FISH or screening assays. The sets with two single-band excitation filters allow for selective excitation, but require the use of excitation filter wheels or sliders. NOTE: sets with multi-band excitation filters are not appropriate for imaging with a monochrome camera.
