1550.12-4 OD6 Ultra Narrow Bandpass Filter



1550.12-4 OD6 Ultra Narrow Bandpass Filter


Narrowband optical interference filter with a 1550.12 nm center wavelength (CWL), a 4 nm full-width at half-maximum (FWHM), and wide-range out-of-band blocking from 780 nm to 1750 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 85% at 1550.12 nm. This unmounted narrowband filter is coated on a 2 mm thick fused silica substrate and is 34 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.
