One of the most commonly used tools used for laser beam focusing in laser fabrication equipment is F-Theta lens. Despite of relatively long lens working distance splatter caused lens contamination is significant if metals are being processed. Windows are designed to protect the lens surface from debris. Being ten to thousand times less expensive than F-Theta lens itself, window is of high importance as protective consumable. Laserand offers variety of standard windows for this purpose. If required protective window is not in the list of standard items, please submit request form for the window you need.
