Optical structures matching the theoretical design through Anteryon’s unique replication technology
Anteryon’s unique glass replication (UV casting) technology is a manufacturing process at room temperature which enables manufacturing of nanometer-scale replicas of optical structures. By using a glass preform the replication technology combines the technical advantages of glass moulding with the design freedom of plastic moulding. The principle of the technology is illustrated in Figure 1.
A glass preform, for example a spherical lens, is pressed into an aspherical mould with a liquid polymer in between. The polymer is then cured with ultraviolet (UV) light and an aspherical lens is pulled from the mould. In this case the polymer is providing a correction on the optical function to make it aspherical.
Besides using a preform to start the replication process it is also possible to replicate on a flat surface. When replicating on a flat surface the polymer will make up the full optical function.
The replication technology provides design freedom for optical structures. More complex optical structures are possible, such as non-rotation symmetric lenses, beam forming optics, micro-lens arrays, binary gratings, free form mirrors and advanced diffractive optical structures.
