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.


Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spetral plot data, please see here for more information.
