Alluxa, Inc. 532.5-2.25 OD3 Ultra Narrow Bandpass Filter 7078

Ultra-narrowband optical interference filter with a 532.5 nm center wavelength (CWL), a 2.25 nm full-width at half-maximum (FWHM), and OD3 out-of-band blocking from 450 nm to 650 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 90% at 532.5 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and is 25 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.
