Notch Filters

StopLine normal-incidence laser-line notch filters deliver extremely high blocking at the laser wavelength (OD6+ typ) whilst providing high transmission and edge sharpness either side of the laser wavelength. They are ideal for applications including Raman spectroscopy, laser-based fluorescence instruments, and biomedical laser systems. Semrock StopLine optical notch filters, made with state-of-the-art Ion Beam Sputtering (IBS), offer a convenient and reliable thin-film format with performance so advanced that they are patented (U.S. patent # 7,123,416). Filters are available in singleband and multiband formats for use at 0 degree incidence.
