794-1.5 OD5

Ultra-narrowband optical interference filter with a 794 nm center wavelength (CWL), a 1.5 nm full-width at half-maximum (FWHM), and OD5 out-of-band blocking from 694 nm to 894 nm. This is a multi-cavity filter with transmission that is greater than 90% at 794 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and is 12.5 mm (± 0.1 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.
