Semrock Optical Filter: NF03-594E  NF03  594E
594 nm StopLine® single-notch filter
Ideal for Raman spectroscopy, laser-based fluorescence instruments and biomedical laser systems, StopLine single-notch filters offer high transmission over ultrawide passbands (UV to 1600 nm). They offer deep laser-line blocking with OD > 6 for maximum laser rejection, and rejected light is reflected for best alignment and stray light control.
