532.1-0.3 OD5

Ultra-narrowband optical interference filter with a 532.1 nm center wavelength (CWL), a 0.3 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 350 nm to 900 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 75% at 532.1 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and is 25.3 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.
