1572.5-1.2 OD5 Ultra Narrow Bandpass Filter



1572.5-1.2 OD5 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 1572.5 nm center wavelength (CWL), a 1.2 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 800 nm to 2100 nm. This is a multi-cavity filter with transmission that is greater than 90% at 1572.5 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick polished Borofloat® substrate and is 50 mm (+0/-0.2 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.
