Optical industry examples - Fresnel lens processing

Laser processing is based on a lens that gathers millions of times the heat equivalent to sunlight to cut, weld and perforate raw materials with non-contact precision and speed.

Laser processing machines with this type of process, which accomplish high production processing characteristics and decisive high cost performance, are rapidly growing in a huge variety of manufacturing business areas. It is the task of our manufacturers of electronic optical components to make the most of the development potential of laser processing machines.

· Circular tools for Fresnel lens machining

The corrugation can be achieved up to 50 nanometres or less, with no chipping of the edge under a 200x microscope. Weise can provide mature configuration tools for diamond single point turning for brands such as American Moore and Japanese Toshiba.

Workpiece name: Fresnel lens

Workpiece material: copper

ND tools
