461-0.45 OD2 Ultra Narrow Bandpass Filter



461-0.45 OD2 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 461 nm center wavelength (CWL), a 0.55 nm full-width at half-maximum (FWHM), and OD2 out-of-band blocking from 415 nm to 510 nm. This is a single-cavity filter with greater than 85% peak transmission. This ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and mounted in a 25.4 mm (+0/-0.2 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.
