Alluxa, Inc. 642 Longpass Dichroic Beamsplitter 7162

Longpass dichroic filter with a 642 nm (± 4.0 nm) cut-on wavelength, greater than 95% average transmittance from 648 nm to 1000 nm, greater than 98% average reflectance from 350 nm to 636 nm, and a steep cut-on edge transition. This dichroic 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 longpass dichroic beamsplitters are designed for use with our fluorescence excitation and emission filters to increase 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.
