Laser CO2 Lenses - Directed Light
Laser CO2 Lenses. Lenses are used in most CO2 laser systems to focus all the beam’s power into a very small spot. Small, focused spot size is important for a couple of reasons: cutting, welding and heat treating generally call for high-power density, and power density is a strong function of spot size. (Reduce the spot diameter by 50% and the ...
