Alluxa, Inc. 666.1-1 OD5 Ultra Narrow Bandpass Filter 7266

Ultra-narrowband optical interference filter with a 666.1 nm center wavelength (CWL), a 1 nm full-width at half-maximum (FWHM), and OD5 out-of-band blocking from 566 nm to 766 nm. This is a multi-cavity filter with transmission that is greater than 90% at 666.1 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.
