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.

Testing has proven to show no signs of degradation when exposed to at least 6.0 W of power from an unfiltered xenon arc lamp over a 25 mm diameter (corresponding to 1.2 W/cm2) for over 500 hrs.
