Beamsplitters divide a beam of light by wavelength, power, or polarization, reflecting a portion through 90° and transmitting the rest. The key to selecting a beamsplitter is finding the right combination of power handling and beam displacement for your application. Our plate and cube beamsplitters are offered with a wide variety of coating options to help you find the ideal fit.
All of our beamsplitters have been designed and manufactured for the highest power handling possible, making use of techniques like optical adhesives, optical contacting, Chemically Activated Direct Bonding (CADB®), and proprietary coating processes to do so.
Coating options include polarizing, laser line non-polarizing, ion beam sputtered, broadband dielectric, and broadband hybrid coatings to give you the breadth and depth of performance you need from a single optics supplier. Each beamsplitter is manufactured to exacting specifications to ensure preservation of beam quality, including low wedge, low transmitted wavefront error or surface figure, and high surface quality (i.e., low scratch and dig). Our UV components use only Corning 7980 UV-grade fused silica.
All of our standard beamsplitters have antireflection coatings matched to the wavelengths of operation at any air-glass interfaces, which both minimizes transmission loss and ghost reflections. Our broadband AR (BBAR) coatings possess a unique combination of low average reflection of ≤0.5% over a very broad range and high damage threshold (10 J/cm2, 20ns, 20Hz @1064nm pulsed; 1 MW/cm2 @1064nm CW).
We understand that every application is unique, which is why we can provide many of our beamsplitters on a semi-custom basis in the precise size, shape, wavelength or split ratio you need. Contact us today to find the catalog, semi-custom or custom solution you need.
