640-77 OD6 Bandpass Filter



640-77 OD6 Bandpass Filter


Bandpass filter with a 640 nm (± 3.5 nm) center wavelength (CWL), a 77 nm full-width at half-maximum (FWHM), and wide-range OD5/OD6 out-of-band blocking from 490 nm to 925 nm. This bandpass filter has steep edges and greater than 93% average transmission from 605 nm to 675 nm. It is coated on a 2 mm thick fused silica substrate and mounted in a standard 25 mm (+0/-0.1 mm) diameter, 3.5 mm (± 0.1 mm) thick anodized aluminum ring. Alluxa OD6 bandpass filters are all designed to increase fluorescence instrument performance, resulting in bright, high contrast images of target molecules. All Alluxa optical filters are highly durable and hard-coated using our innovative SIRRUS™ plasma deposition process. Contact us for custom sizing.
