Expertise in micro and nanotechnology and deep understanding of optical science has enabled TTP to develop a range of innovative  optical coatings.  One example is the well-known "Motheye" nano-structure – a technique for coating an optical surface, such as a spectacle lens, to give it anti-reflective (AR) properties.

The challenge was to create a physical structure on the curved surface of the base material of a spectacle lens so that the optical reflectivity was minimised and the coating was more resistant to scratching than standard dielectric coatings. We developed the design of the nanostructured coating to provide the anti-reflection performance and tune the residual colour as well as creating the manufacturing process that allows such high technology coating to be created on the surface of the lens at low cost consistent with a consumer product.

We have also pioneered other techniques of creating coatings of micro and nanostructures. These include high-density micro-lens arrays for displays where we developed high power laser systems and processes to create optical quality high fidelity structures in hard metals as master tooling for embossing processes.
