532.3-0.2 OD7 Ultra Narrow Bandpass Filter

Ultra-narrowband optical interference filter with a 532.3 nm center wavelength (CWL), a 0.2 nm full-width at half-maximum (FWHM), and wide-range OD7 out-of-band blocking from 300 nm to 900 nm. This is a single-cavity filter with greater than 80% peak transmission. This ultra-narrowband filter is coated on a 2 mm thick Borofloat® substrate and mounted in a 50.8 mm (+0/-0.8 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.
