325 nm laser BrightLine® single-edge laser dichroic beamsplitter

Semrock部件编号: Di01-R325-25x36

IDEX部件编号: FL-006896

The perfect dichroic 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, and anti-reflection (AR) coatings to minimize imaging artifacts resulting from the coherent laser light. This laser dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.
