NewOpto offers Multiphoton Fluorescence Filter, which virtually eliminates excitation laser noise at the detector. To reduce undesired fluorescence noise outside a desired band, simply add a bandpass filter. Unless otherwise noted, all filters are housed in a standard 25mm round black-anodized aluminum right with thickness as indicated, and a clear aperture of at least 21mm.
