488/543/635 nm lasers BrightLine® triple-edge laser dichroic beamsplitter

Semrock Logo

Optimized beamsplitters for the most popular lasers used in fluorescence imaging, including newer all-solid-state lasers for conventional laser based microscopy such as confocal imaging. 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 dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.
