A line of notch filters for 488, 514, 532, and 561 nm lasers ensures effective blocking of the designated laser wavelength and feature OD >6.0. While the notch filter rejects a very narrow wavelength range, which is typically 15–20 nm at FWHM, it has high transmission in broad bandpass ranges. The backside of the filter is broadband antireflection-coated to minimize the reflection at passband regions. Applications include Raman spectroscopy, medical laser systems, laser safety applications, and laser-based fluorescence instruments.
