Alluxa, Inc. 558_658 ULTRA Dualband Dichroic Beamsplitter 7181

ULTRA Series dualband dichroic filter with 558 nm (± 3.0 nm) and 658 nm (± 4.0 nm) cut-on wavelengths, steep edge transitions, greater than 93% average transmittance from 564 nm to 592 nm and 665 nm to 725 nm, and greater than 95% average reflectance from 470 nm to 547 nm and 615 nm to 646 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.
