Fabrication of 3D nanostructures with an accuracy of 0.2 µm in different materials
TOWA is always developing new technologies in order to meet customers’ requirements in the area of ultra-precision manufacturing.
Since the last few years TOWA noticed requirements for applying complex 3D nanostructures in different materials. Through molding, micro-milling and micro-grinding TOWA is able to apply 3D nanostructures with an accuracy of 0.2 µm in a processing area of maximum 450mm x 450mm in various materials. The nanostructures are often required for medical instruments, optical, fibers, polymer MEMS, molds for nano-imprinting and optical lenses.
An application example of an optical lens is a micro lens array which is used for head up displays for cars. The dashboard information is projected in to the micro lens array which will reflect the dashboard information on the windshield.
