Description
Description
Ultra-narrowband optical interference filter with a 829.375 nm center wavelength (CWL), a 0.5 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 200 nm to 1050 nm. This is a multi-cavity filter with transmission that is greater than 80% at 829.375 nm. This ultra-narrowband filter is coated on a 2 mm thick polished 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.
