CO₂ Laser Optics/Parts
CO₂ Laser High Power Focusing Lens
ZnSe is the typical material for high power CO laser optics for its low absorption coefficient in infrared wavelengths and its visible transmission. High transmission and ultra low absorption coating is added to further reduce surface reflection and absorption of laser power. It is widely used for CO laser cutting, welding and laser heat treatment. LZ series ZnSe Plano-Convex lenses have a positive focal length, they are used to focus a collimated beam to a small spot size, the curved surface will be faced to the input beam to minimize spherical aberration.

CO₂ Laser Telecentric Scan Lens
Telecentric scanning lenses are special configurations in which the arrangement of optics is designed to focus down the beam so that it is always perpendicular to the flat field. This is accomplished by ensuring that the system 'stop' is located at the front focal point of the lens system. The 'stop' is located at the position where the beam is deflected from the axis. In a single-axis scanning system, this location is at the scanning mirror. For two-axis scanning, the stop is mid -way between the mirrors. Adaptors for major scan head providers are available upon request.

CO₂ Laser Singlet F-Theta Scan Lens
F-Theta lenses are commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. Typically the F-Theta distortion of the lens is kept less than 1% so that it is able to produce a precise spot in the flat field on the image plane.

CO₂ Laser Doublet F-Theta Scan Lens
Doublet F-Theta scanning lenses provide better performance than a singlet. It has more even spot size and less spot distortion over the scan field. We use ZnSe or GaAs for this series of scan lenses. Lens adaptors for major scan head providers are available upon request.
