1031.2-0.6 OD8

Ultra-narrowband optical interference filter with a 1031.2 nm center wavelength (CWL), a 0.6 nm full-width at half-maximum (FWHM), and OD8 out-of-band blocking from 940 nm to 1130 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 85% at 1031.2 nm. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® 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.
