473-1.5 OD7 Ultra Narrow Bandpass Filter



473-1.5 OD7 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 473 nm center wavelength (CWL), a 1.5 nm full-width at half-maximum (FWHM), and OD7 blocking from 475 nm to 585 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 90% at 473 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick polished Borofloat® substrate and is 25.4 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.
