  • Your filter spectrum may differ slightly from the typical spectrum above, but is certified to meet the optical specifications noted below.
  • Note that the change in blocking at 1120 nm is due to a change in the detector on the measurement equipment; the filter meets all optical specifications noted below.

850/310 nm BrightLine® SRS imaging emission filter
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.
