Alluxa, Inc. 630.2-0.5 OD6 Ultra Narrow Bandpass Filter 7259

Ultra-narrowband optical interference filter with a 630.2 nm center wavelength (CWL), a 0.5 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 400 nm to 1000 nm. This is a multi-cavity filter with exceptionally steep edges and transmission that is greater than 85% at 630.2 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick N-BK7 substrate and is 25 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.
