738 nm edge BrightLine® single-edge image-splitting dichroic beamsplitter for standard microscopy

Semrock Logo

BrightLine® image-splitting dichroic beamsplitters offer superb image quality for both transmitted and reflected light when separating beams of light by color for simultaneous capture of multi-color images. For applications such as (FRET) and real-time live-cell imaging, users can now separate two, four or even more colors onto as many cameras or regions of a single camera sensor. The exceptional flatness of these filters virtually eliminates aberrations in the reflected beam for most common imaging systems. Common Fluorophore Pair to Split: Cy5.5/Cy7 FF738-FDi01-t1 image-splitting dichroic beamsplitter for standard micrscopy available on 1 mm substrate for reflecting imaging beams up to 10 mm in diameter while minimizing RWE
