F-theta Scan Lens for CO2 laser - Triple elements made of ZnSe
SL3 Series F-Theta scanning lenses consist of three ZnSe elements with or without protective window; they can reduce spot distortion and achieve more even spot size over the scanning field compared to SL1 and SL2. SL3 is used for finer CO2 laser applications like electronic micro processing. Lens adaptor for major scan head providers are available upon request.

Remark: The spot size is simulation result, it does not reflect the actual spot size on workpiece as the simulation does not consider the material properties and how the laser being absorbed during machining.
