Cube Beamsplitters
Excelitas offers precision fabrication and coating techniques that enable us to create high performance cube beamsplitters that provide a unique combination of superior optical performance and high laser damage resistance. With the use of our proprietary adhesive-free Activated Covalent Bonding (ACB) technology assembly process, Excelitas cube beam splitters provide outstanding environmental stability and durability. They are available in the UV, VIS, NIR as well as narrow or broad bandwidth operation in the mid-infrared.
Available in a wide range of standard sizes, our UV, VIS and NIR laser line cube beamsplitters can be customized from 1mm up to 125mm within the wavelength range of 266 nm to 2000 nm.
Our mid-infrared precision cube beamsplitters provide high laser damage threshold, high transmission ( >95% ) and high extinction ratios ( >100,000:1 ). Custom cubes utilizing our proprietary adhesive free bonding technique are available in the 1 mm to 75 mm size range with LDT that is only limited by the bulk material. These optics are suitable for use anywhere from cryogenic environments to industrial, military, and spaceborne applications.
