Research Objectives
The development of nanotechnology has led to the development of nanostructured devices. We are engaged in research and development of nanostructured optical functional devices and research activities to bridge the technology to society by forming nanostructures on the surface of curved lens molds and developing micro molding technology by integrating machining technology and MEMS semiconductor technology. From these efforts, we aim to create a nanostructured device industry.
Research Results
By combining material alloy technology and thin-film vacuum technology, we have realized curved molds with nanostructures. We are also developing technology to achieve anti-reflective performance through molding alone, using injection molding and nanoimprinting. With this technology, we are developing optical components that combine low reflection and antifogging properties in a wide range of angles with reflection reduction up to 60 degrees, the highest level in the world.
