Mirrors and Lenses

These lenses are economical and work great for general purpose cutting and most engraving. The shorter focal lengths yield smaller spot sizes, typical for higher DPI engraving. Longer focal lenses perform more as a deeper cutting knife. The typical laser machine is shipped with a standard 55mm lens (CO2LENS-20-55). Specifications for Standard Lenses:           20mm Diameter Nominal           1.8mm Edge Thickness           Coating: ZnSe (Zinc Seleni..

These higher precision lenses have a significantly better core material and coating which produce a smaller spot size, block less laser light, and yields a longer life. Specifications for Premium Lenses:           20mm Diameter           1.8mm Edge Thickness           Coating: ZnSe (Zinc Selenium)           For 10.6um CO2 Wavelength           Shape: Plano ..

The Focal-tube assembly includes the Focal-tube, lens washer, lens nut, standard air nozzle, and air fitting. This does not include lens. The focal tube assembly is nice to have if the machine operator switches between using lenses of different focal length and does not like switching the lenses into the same tube assembly. The lenses can be mounted in two separate assemblies and so can switched in a matter if less than one minute.   Focal-Tube Assembly: $55 (Does not include Lens)  Lens Diameter = 20mm, Barrel Diameter = 21mm,  Preferred Lens Focal Length = 55-63..
