856.625-0.75 OD6 Ultra Narrow Bandpass

Description

Details
Ultra-narrowband optical interference filter with a 856.625 nm center wavelength (CWL), a 0.75 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 200 nm to 1200 nm. This is a multi-cavity filter with exceptionally steep edges, a flat top, and transmission that is greater than 85% at 856.625 nm. This unmounted ultra-narrowband filter is coated on a 0.7 mm thick Borofloat® substrate and is 12.6 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.
