Dual-notch filters are ideal for laser-based fluorescence instruments, confocal and multi-photon fluorescence microscopes, and analytical and medical laser systems. These filters offer high transmission over wide passbands. They offer deep laser-line blocking for maximum laser rejection, and rejected light is reflected for best alignment and stray light control.
