CO2 Lenses

Product options designed for maximum efficiency in different material and cutting processes;

The type of material used in CO2   laser cutting machines and the power of the machine are  important factors for  the optical life of the lens. During  the cutting process, a part of the laser beam  passing through the lens and focusing is absorbed  by  the lens.  As a result of this absorption, the heated lens expands and  optical focusing distance changes. The efficiency  of the lens decreases over time.  If the machine which is using the lens is a high power machine designed for  cutting thick mateials; the energy absorbed by the lens will increase and the decrease in efficiency will accelerate. Since the reflection  is high in materials such as aluminum and stainless steel, the beam  passing over  the lens will reflect back and cause the lens to heat more.

In order to minimize these factors, there are 3 different lens options devoloped by Ophir.
