BARRINGTON, N.J., Feb. 13, 2012 — Edmund Optics has introduced its TechSpec OD 6 laser-line bandpass filters, which provide the high transmission and deep rejection necessary to isolate narrow spectral regions for a variety of applications. Featuring a bandwidth as low as 2 nm, they offer maximum transmission of stimulated emission and are fabricated using “hard” ion-beam sputtering technology, ensuring high performance and good durability. They achieve >90% transmission at their specified design laser wavelength and offer blocking of >6 optical density (OD) at 1.5% of the laser wavelength. They are designed to eliminate noisy spontaneous emission, and they provide a full width half maximum as narrow as 2 nm. They can be used in laser-based fluorescence instrumentation and Raman spectroscopy, as well as in analytical and medical laser systems. They are available with center wavelengths of 532, 785 and 1064 nm, and with diameters of 12.5 and 25 mm. They are in-stock and available for immediate delivery.
