Ultra-narrowband optical interference filter with a 589.2 nm center wavelength (CWL), a 2 nm full-width at half-maximum (FWHM), and wide-range OD4 out-of-band blocking from 400 nm to 1400 nm. This is a multi-cavity filter with transmission that is greater than 95% at 589.2 nm. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and mounted in a 25 mm (+0/-0.1 mm) diameter, 3.5 mm (± 0.1 mm) thick anodized aluminum ring. 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.
