354.72-1 OD8 Ultra Narrow Bandpass Filter



354.72-1 OD8 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 354.72 nm center wavelength (CWL), a 1 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 200 nm to 1200 nm. This filter is designed to attenuate 532.08 nm and 1064.15 nm laser lines and elastic backscatter signals to a level of OD8. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 75% at 354.72 nm. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and mounted in a 25.4 mm (+0/-0.2 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.
