652-3 OD6 Ultra Narrow Bandpass Filter



652-3 OD6 Ultra Narrow Bandpass Filter


Narrowband optical interference filter with a 652 nm center wavelength (CWL), a 3 nm full-width at half-maximum (FWHM), and OD6 out-of-band blocking from 590 nm to 730 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 90% at 652 nm. This unmounted narrowband filter is coated on a 2 mm thick Borofloat® substrate and is 50 mm (± 0.1 mm) in diameter. 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.
