For optimal filter set performance, pair this emitter with AF01-633/40 and AF659-Di01, which have been optimized for Cy5™, Alexa Fluor 647, and other key fluorophores. Precise edge placement of the steep spectral edges combined with deep complementary blocking maximize fluorophore performance compared to standard exciter and emitter pairs.
