1065-1.8 OD6

Ultra-narrowband optical interference filter with a 1065 nm center wavelength (CWL), a 1.8 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 800 nm to 1300 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 90% at 1065 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and is 25.4 mm (+0/-0.2 mm) in 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.
