Fabricated using hard ion beam sputtering technology, the TECHSPEC OD 6 laser line bandpass filters provide the high transmission and deep rejection necessary to isolate narrow spectral regions for use in a wide variety of applications. Highly durable, they achieve greater than 90% transmission at their specified design laser wavelength. Manufactured by Edmund Optics, the filters offer blocking of >6.0 optical density at just +1.5% of the laser wavelength. Designed to offer maximum transmission of stimulated emission, while eliminating noisy spontaneous emission, they provide a full width half maximum (FWHM) as narrow as 2 nm. Suitable for use in laser-based fluorescence instrumentation and Raman spectroscopy, as well as in analytical and medical laser systems, the filters are available with center wavelengths of 532, 785 and 1064 nm with diameters of 12.5 and 25 mm.
