Alluxa, Inc. 354.7-0.35 OD4 Ultra Narrow Bandpass Filter 7707

Ultra-narrowband optical interference filter with a 354.7 nm center wavelength (CWL), a 0.35 nm full-width at half-maximum (FWHM), and wide-range OD4 out-of-band blocking from 200 nm to 950 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 75% at 354.7 nm. This unmounted ultra-narrowband filter is coated on a 5 mm thick fused silica substrate and is 38.1 mm (± 0.1 mm) in diameter. Alluxa ultra-narrow bandpass filters have the highest transmission and narrowest bandwidths currently available. And because they are hard-coated using our innovative SIRRUS™ plasma deposition process, all Alluxa optical filters are highly durable and resistant to laser damage.
