CO2 Laser Lenses

CO2 Laser Lenses

Excelitas high-precision infrared CO2 laser lenses are customized from a variety of substrate materials, including Ge, ZnSe, ZnS, and Cleartran. Using our substrate fabrication and coating leading-edge process technologies, our CO2 laser lenses minimize subsurface damage for excellent Laser Damage Thresholds. 

Excelitas consistently delivers optics with exceptional laser damage resistance characteristics due to our highly controlled processes for fabricating, coating, and laser-damage testing in our state-of-the-art facilities, with a unique capability of in-house laser damage testing. This vertical integration is critical for enabling careful control over every aspect of the design and manufacturing process to achieve a high damage threshold reliably. This process includes precise specification and thorough inspection of incoming raw materials, followed by shaping and polishing the components to minimize subsurface damage and contamination. Thin film coatings are then designed and deposited using our techniques that avoid contamination and limit electric field effects. In addition, our broad well-equipped in-house laser damage testing lab includes several different laser pulse widths and wavelengths.
