589.5-1 OD4 Ultra Narrow Bandpass

Description

Details
Ultra-narrowband optical interference filter with a 589.5 nm center wavelength (CWL), a 1 nm full-width at half-maximum (FWHM), and wide-range OD4 out-of-band blocking from 400 nm to 1000 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 90% at 589.5 nm. This ultra-narrowband filter is coated on a 3.3 mm thick polished Borofloat® substrate and mounted in a 25.4 mm (+0/-0.2 mm) diameter, 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.
