F-Theta Scan Lens - CO2 Laser (Double Elements)

 

Doublet F-theta Scanning lenses provide better performance than a singlet. It has more even spot size and less distortion over the scan field. We use ZnSe or GaAs for this series of scan lens. Lens adaptor for major scan head providers are available upon request.
