Key Performance Features

This dichroic beamsplitter provides high transmission in the red/NIR (660–850nm) for Cy5, Alexa 647, or laser channels, while steeply blocking and reflecting visible/green excitation (<1% T from 400–635nm). The 45° AOI ensures optimal system compatibility for upright/inverted fluorescence microscopes, laser scanning, and multi-color imaging platforms. The 1.1mm thickness balances rigidity with minimal optical path shift, perfect for dense OEM and research assemblies.

Applications

- Multi-channel confocal and widefield microscopy: Efficiently separates far-red emission from green/yellow excitation and background. - Flow cytometry panels: Supports clear channel separation and minimal cross-talk for multi-laser cell sorting. - Laser platforms and spectroscopy: Robust dichroic for splitting or combining 647nm, 660nm, and NIR beams. - OEM fluorescence system integration: Fast customization and reliable supply for system builders and manufacturers.
