Custom 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.

Excelitas non-polarizing cube beamsplitters deliver broadband, polarization insensitive operation and exceptional path length matching for reflected and transmitted beams. Our unique adhesive-free Activated Covalent Bonding (ACB) process, together with a series of high precision, proprietary fabrication techniques, enable consistency across cubes with subarcminute beam deviation accuracy and low wavefront distortion.

Excelitas high precision beamsplitter assemblies provide low transmitted wavefront distortion, minimal beam deviation, and precise control of output beam phase relationships. These beamsplitter assemblies allow multiple beams to be combined, split, or redirected based on wavelength and/or polarization. Using our adhesive free Activated Covalent Bonding (ACB) process, our beamsplitter assemblies provide very high laser damage resistance with exceptional thermal and environmental stability making them ideal for applications in aerospace, defense, semiconductor manufacturing, analytical instruments and industrial laser systems.

Excelitas offers custom thin film polarizers for the applications across UV and the infrared. Utilizing our extensive fabrication and thin film coating technology and expertise, our polarizers provide exceptional extinction ratio, ultra-low loss, superior wavefront performance and high laser damage resistance. Careful control of all aspects of component fabrication, from polishing through coating, ensures optimal system level performance.
