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.
