ULTRA Series dualband dichroic filter with 498 nm (± 3.0 nm) and 653 nm (± 4.0 nm) cut-on wavelengths, steep edge transitions, greater than 93% average transmittance from 505 nm to 570 nm and 663 nm to 850 nm, and greater than 95% average reflectance from 350 nm to 491 nm and 600 nm to 643 nm. This polychroic filter is designed for use at a 45 degree angle of incidence (AOI). It is coated on a 1.04 mm fused silica substrate and is 25.2 mm x 35.6 mm (± 0.1 mm) in size. Alluxa ULTRA Series longpass dichroic beamsplitters are designed for use with our fluorescence excitation and emission filters to optimize 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.
