1053-4 OD6 Ultra Narrow Bandpass Filter



1053-4 OD6 Ultra Narrow Bandpass Filter


Narrowband optical interference filter with a 1053 nm center wavelength (CWL), a 4 nm full-width at half-maximum (FWHM), and OD6 out-of-band blocking from 945 nm to 1200 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 90% at 1053 nm. This narrowband filter is coated on a 2 mm thick fused silica 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.
