395.7-0.3 OD12 Ultra Narrow Bandpass Filter



395.7-0.3 OD12 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 395.7 nm center wavelength (CWL), a 0.3 nm full-width at half-maximum (FWHM), and wide-range out-of-band blocking from 300 nm to 1100 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 70% at 395.7 nm. This ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and mounted in a 25 mm (+0/-0.1 mm) diameter, 3.5 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.
