486.4-0.3 OD6

Ultra-narrowband optical interference filter with a 486.4 nm center wavelength (CWL), a 0.3 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 200 nm to 1100 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 85% at 486.4 nm. This ultra-narrowband filter is coated on a 2 mm thick polished Borofloat® substrate and mounted in a 50.8 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.
