Ultra-narrowband optical interference filter with a 515 nm center wavelength (CWL), a 0.15 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 390 nm to 1000 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 90% at 515 nm. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate. This 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 of our optical filters are highly durable and resistant to laser damage.
