Summary Box:

ULTRA Series longpass dichroic beamsplitters with cut-on wavelengths available from 409nm to 766nm.

Description:

ULTRA Series longpass dichroic beamsplitters exhibit greater than 98% average reflectance and an exceptionally steep cut-on edge transition. These dichroic filters are 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 more customised options.
