Laser-Line Cleanup Filters
Edmund Optics has announced TechSpec OD 6 laser-line cleanup filters for use with common gas and solid-state lasers. They provide the high transmission and deep rejection necessary to isolate narrow spectral regions in a variety of applications.
The bandpass filters are fabricated using hard-coated plasma deposition technology for durability. They achieve >90% transmission at their specified design laser wavelength and offer blocking of >6 optical density at 1.5% of the laser wavelength.
With steep edges, they offer maximum transmission of stimulated emission, while eliminating noisy spontaneous emission. They can be used in laser-based fluorescence instrumentation, Raman spectroscopy, and in analytical and medical laser systems.
The filters are available with center wavelengths of 325, 355, 488, 514, 532, 632, 785, 808, 830, 980 and 1064 nm, with diameters of 12.5 and 25 mm.
