Alluxa's ULTRA Series of fluorescence filters are designed to provide the highest level of performance currently available for off the shelf products. ULTRA Series filters provide better overall performance than our standard fluorescence filters by using a combination of tight wavelength control (typically ± 1.5 nm), ultra-steep edges, deeper blocking, and the industry's highest transmission levels. They are also specified to produce zero pixel shift when imaging multiple fluorophores. ULTRA Series filters will optimize fluorescence instrument performance, resulting in bright, high contrast images of target molecules. All of Alluxa's filters are durable and hard-coated using a proprietary deposition process.

Ultra-narrowband optical interference filter with a 307.7 nm center wavelength (CWL), a 0.5 nm full-width at half-maximum (FWHM), and OD4 out-of-band blocking from 200 nm to 500 nm. This is a multi-cavity filter with transmission that is greater than 65% at 307.7 nm. This ultra-narrowband filter is coated on a 2 mm thick fused silica substrate and mounted in a 25.4 mm (+0/-0.2 mm) diameter, 5 mm (± 0.1 mm) thick anodized aluminum ring. Alluxa ultra-narrow bandpass filters have the highest transmission and narrowest bandwidths currently available. And because they are hard-coated using our innovative SIRRUS™ plasma deposition process, all Alluxa optical filters are highly durable and resistant to laser damage.
