458-2 OD5 Ultra Narrow Bandpass Filter



458-2 OD5 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 458 nm center wavelength (CWL), a 2 nm full-width at half-maximum (FWHM), and OD5 out-of-band blocking from 410 nm to 510 nm. This is a multi-cavity filter with moderately steep edges, a flat top, and transmission that is greater than 90% at 458 nm. This ultra-narrowband filter is coated on a 1.05 mm thick fused silica 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.
