475-28 OD6

ULTRA Series bandpass filter with a 475 nm (± 1.5 nm) center wavelength (CWL), a 28 nm full-width at half-maximum (FWHM), and wide-range OD6 out-of-band blocking from 300 nm to 700 nm (with additional blocking up to 950 nm). This bandpass filter has exceptionally steep edges and greater than 95% average transmission from 463 nm to 487 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.
