436.5-49_521-22_604-30_704-54_810-85 OD6

ULTRA Series penta-bandpass filter with 436.5 nm, 521 nm, 604 nm, 704 nm, and 810 nm center wavelengths (CWL) and full-width at half-maximums (FWHM) of 49 nm, 22 nm, 30 nm, 54 nm, and 85 nm, respectively. This quadband optical filter has exceptionally steep edges, greater than 93% average in-band transmission, and wide-range OD6 out-of-band blocking from 380 nm to 1050 nm (and additional out-of-band blocking from 200 nm to 1100 nm). It is coated on a 2 mm thick polished Borofloat® substrate and mounted in a standard 25 mm (+0/-0.1 mm) diameter, 3.5 mm (± 0.1 mm) thick anodized aluminum ring. Alluxa ULTRA Series fluorescence filters are designed to optimize fluorescence instrument performance, resulting in bright, high contrast images of target molecules. ULTRA Series filters provide better overall performance than our standard fluorescence filters by using a combination of tight wavelength control, ultra-steep edges, deeper blocking, and the industry’s highest transmission levels. All Alluxa optical filters are highly durable and hard-coated using our innovative SIRRUS™ plasma deposition process. Contact us for custom sizing.
