483-40 OD6 ULTRA Bandpass Filter
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.

*Auxiliary blocking typical based on the displayed spectrum.
