Alluxa, Inc. 396.92-0.37 OD6 Ultra Narrow Bandpass Filter 7335

Ultra-narrowband optical interference filter with a 396.92 nm center wavelength (CWL), a 0.37 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 300 nm to 1200 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 85% at 396.92 nm. This ultra-narrowband filter is coated on a 3 mm thick N-BK7 substrate and mounted in a 30 mm (± 0.1 mm) diameter, 5 mm (± 0.1 mm) thick anodized aluminum ring. 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.
