587.6-1.5 OD6 Ultra Narrow Bandpass Filter



587.6-1.5 OD6 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 587.6 nm center wavelength (CWL), a 1.5 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 200 nm to 1100 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 90% at 587.6 nm. This unmounted ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and is 20 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.
