High Performance Laser-Line Bandpass Filters

Our high performance laser-line filters set the new standard in bandpass filter performance and reliability. Fabricated using a patent-pending “hard” ion-beam sputter technology, these filters achieve >90% transmission at the design laser wavelength, and offer blocking of >5.0 OD at just ±1% of the laser wavelength. These filters are ideal for laserbased fluorescence instrumentation, Raman spectroscopy, and analytical and medical laser systems. Designed to offer the maximum transmission of stimulated emission while eliminating noisy spontaneous emission, the steep edges make these filters the perfect complement to our Laser Line Longpass and Rugate Notch Filters.
