Laser Optics and Selecting the Proper Lens for your CO2 .. - co2 laser focal point ,You need to select the lens that is most appropriate for your application.. In the illustration, I'm showing three lenses that will show different focal lengths and you will see how this changes the properties of the converged laser beam.. I will show these as a 2" focal length, 3" focal length and a 4" focal length..Laser Optics and Selecting the Proper Lens for your CO2 Appl ..

1..The adjustment of laser cutting machine focusing points.. It is very important to adjust focus point properly in the process of laser cutting.. because relative position between laser beam focus and the surface of work piece have a great influence on cutting quality.. We can try to cut by changing the focus point, when there is no dross on the ..
The feasibility to automatically optimize the focal point position is analyzed.. Preliminary tests demonstrate that neural networks can be used to optimize the focal point position with good accuracy in CW CO2 laser welding..
1.. Terminology.. The CO2, or carbon dioxide, laser is a member of the gas laser group.. The CO2 laser emits in mid-infrared between ~9µm to ~11µm wavelength, the strongest emission line is often 10..6µm (more rarely at 9..3µm or 10..2µm).. Together with Nd: YAG/fiber lasers, the CO2 laser creates the backbone of industrial laser technology..

For lasers with infrared wavelengths, such as, for example, 10..6 µm in CO 2 lasers, lenses and windows made of zinc selenide (ZnSe) are used.. Silicon or copper mirrors are used as mirrors.. Phase shift mirrors used to produce circular polarisation are also available.. Beam expanders and diffractive elements for beam shapes complete our product ..
