Alluxa, Inc. 409 Longpass Dichroic Beamsplitter 7161

Longpass dichroic filter with a 409 nm (± 3.0 nm) cut-on wavelength, greater than 95% average transmittance from 415 nm to 850 nm, greater than 98% average reflectance from 325 nm to 403 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.
