484 nm edge BrightLine® single-edge image-splitting dichroic beamsplitter for standard microscopy
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. This dichroic beamsplitter is optimized for reflecting imaging beams up to 10 mm in diameter while minimizing RWE.
