1080-0.2 OD3 Ultra Narrow Bandpass Filter

Ultra-narrowband optical interference filter with a 1080 nm center wavelength (CWL), a 0.2 nm full-width at half-maximum (FWHM), and wide-range OD3 out-of-band blocking from 980 nm to 1180 nm. This is a single cavity filter with moderately steep edges, a flat top, and transmission that is greater than 90% at 1080 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and and is 25.5 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.
