521-36_638-88 OD6

Dual-bandpass filter with center wavelengths (CWL) at 521 nm and 638 nm, each specified with a ± 4.0 nm tolerance, and full-width at half-maximums (FWHM) of 36 nm and 88 nm for each respective passband. This dualband optical filter has steep edges, greater than 90% average transmission, and wide-range OD6 out-of-band blocking from 200 nm to 900 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.
