499_654 ULTRA Dualband Dichroic Beamsplitter

Description

Details
ULTRA Series dualband dichroic filter with 499 nm (± 3.0 nm) and 654 nm (± 4.0 nm) cut-on wavelengths, steep edge transitions, greater than 93% average transmittance from 509 nm to 545 nm and 664 nm to 890 nm, and greater than 95% average reflectance from 390 nm to 489 nm and 574 nm to 644 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.
