521 nm Avant™ Dichroic Beamsplitter

Semrock Logo

For optimal filter set performance, pair this dichroic with AF01-504/24 and AF01-539/27, which have been optimized for Yellow Fluorescent Protein (YFP), Venus, and other key fluorophores. Precise edge placement of the steep transition edge combined with very high reflection and transmission bands maximize fluorophore performance compared to standard dichroics.
