Alluxa, Inc. 1565.4-1 OD6 Ultra Narrow Bandpass Filter 7776

Ultra-narrowband optical interference filter with a 1565.4 nm center wavelength (CWL), a 1 nm full-width at half-maximum (FWHM), and wide-range OD6 Abs out-of-band blocking from 700 nm to 1800 nm. This is a multi-cavity filter with transmission that is greater than 85% at 1565.4 nm. This ultra-narrowband filter is coated on a 3 mm thick Fused Silica substrate with a 25 mm (+0/-0.1 mm) 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.
