680 nm blocking edge BrightLine® multiphoton short-pass emission filter

Semrock Part Number: FF01-680/SP-25

IDEX Part Number: FL-009655  /

Semrock
Ultrahigh-performance multiphoton fluorescence filters that accommodate a wide range of fluorescence dyes. Designed to be a fixed component in any multiphoton or nonlinear (harmonic-generation) microscope, so that when desired individual, narrower bandpass filters can be added without having to worry about the near-IR blocking of these filters. The transmission bands of these short-pass emitters are so wide, they appear clear at normal incidence.
