Light Tunnel Generator


Save costs by improving the efficiency and effectiveness of high power laser cutting. Use the PowerPhotonic Light Tunnel Generator to create a ring shaped spot that is maintained over such a long distance that it creates a light tunnel. Light Tunnel Generators from PowerPhotonic are thin glass windows with a unique (patent applied for) precision freeform surface that are designed to be mounted inside a cutting or welding head.They are a perfect solution to the problem of creating a ring shaped intensity profile that persists over 10’s of mm – far into metal that is being laser cut (or welded). We have standard products for collimated high power fiber lasers operating at 1070nm up to 20kW CW power.

Our design and manufacturing process makes it easy for variations of standard products to be created. We can quickly modify designs to work for different beam diameters up to 50mm and/or to work in diverging (or converging) beams.
