Beam splitters separate a beam of light by wavelength, power, or polarization into two orthogonal beams. The properties of the divided beams depend both on the beam splitter coating and on the mechanical characteristics of the plate or cube upon which it has been coated. Here at CVI Laser Optics, we have combined our expertise in the manufacture of quality optics with our many optical coatings to create a broad range of beam splitters available off the shelf for the most common applications in research or prototyping.
We can also work with you one-on-one to develop custom beam splitters for a specific experiment or new product development. Our expert technical staff will guide you through the many options we offer, ranging from custom split ratios, unique materials, and custom coatings to unusually large or small dimensions. We understand that high laser damage threshold and beam displacement are important considerations when incorporating a beam splitter into a new optical design, and will work with you to navigate our options for beam splitter construction, coatings, and surface quality to strike the optimum balance between cost and performance. Beam splitter coatings can even be applied to our wedged and plane parallel substrates for OEM applications. High quality antireflection coatings are also available on all of our beam splitters to aid maximum throughput and power handling.
