635 nm laser BrightLine® single-edge laser-flat dichroic beamsplitter
The perfect beamsplitters for the most popular lasers used in fluorescence imaging, including newer all-solid-state lasers. All beamsplitters in this category have exceptional reflectance at the laser wavelengths, "laser-grade" flatness, and anti-reflection (AR) coatings to minimize imaging artifacts resulting from the coherent laser light.
