The DM700-1.1mm-AOI45° dichroic beamsplitter is engineered for advanced multi-wavelength, NIR, and visible-channel separation. With transmission greater than 95% from 715–900nm, blocking at less than 1% from 350–675nm, and a precise 45° angle of incidence (AOI), this optic is ideal for dual-laser, NIR fluorescence, and multi-color microscopy platforms requiring ultra-flat transmission and crosstalk-free channel division.

Key Performance Features
This dichroic beamsplitter delivers near-infrared (NIR) and far-red channel separation with >95% transmission in the critical 715–900nm band—ideal for Cy5.5, Alexa 700, or 785/808nm laser lines. The broad<1% blocking band from 350–675nm eliminates crosstalk from green/yellow/visible channels and allows confident imaging or laser splitting even under high-intensity conditions. Its 45° AOI is compatible with standard microscopy and instrument layouts, and the 1.1mm thickness offers strong mechanical stability for dense filter cubes or OEM optics holders.
Applications
- Multi-color fluorescence/confocal microscopy: Clean separation for NIR, far-red, and visible spectrum fluorophores. - Laser path management: Efficient beam combining/splitting for dual/NIR laser systems. - Flow cytometry and cell sorting: Minimized bleed-through in high-parameter panels. - OEM instrument builds: Fast custom sizing/support for complex illumination or detection arrays.
