395.1-1.3 OD5

Ultra-narrowband optical interference filter with a 395.1 nm center wavelength (CWL), a 1.3 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 300 nm to 1200 nm. This is a multi-cavity filter with transmission that is greater than 80% at 395.1 nm. This ultra-narrowband filter is coated on a 3 mm thick N-BK7 substrate and mounted in a 32 mm (± 0.1 mm) diameter, 7 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.
