Description
Ultra-narrowband optical interference filter with an 830 nm center wavelength (CWL), a 0.4 nm full-width at half-maximum (FWHM), and wide-range OD5 out-of-band blocking from 600 nm to 1200 nm. This is a single-cavity filter with greater than 90% peak transmission. This ultra-narrowband filter is coated on a 2 mm thick 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.
