604 nm Avant Dichroic Beamsplitter

Semrock Part Number: AF604-Di01-25x36

IDEX Part Number: FL-429647  /

Semrock
For optimal filter set performance, pair this dichroic with AF01-585/29 and AF01-626/35, which have been optimized for Texas Red, Alexa Fluor 594, ATTO 590 and other key fluorophores when used as a filter set. Precise edge placement of the steep transition edge combined with very high reflection and transmission bands maximize fluorophore performance compared to standard dichroics.
