935.4-0.45 OD5 Ultra Narrow Bandpass Filter



935.4-0.45 OD5 Ultra Narrow Bandpass Filter


Ultra-narrowband optical interference filter with a 935.4 nm center wavelength (CWL), a 0.45 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 250 nm to 1400 nm. This is a multi-cavity filter with steep edges, a flat top, and transmission that is greater than 85% at 935.4 nm. 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, 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.
