Nanoimprinting is a precision transfer technology that is used to form nanometer-sized structures on the surface of a base material. By changing the shape of the nanostructure, we can create products with a range of useful functions. (Fig. 1)
Using simulation and evaluation technologies cultivated over years in the business of optical film manufacturing, we're engaged in development of optical products that function in various ways.
We recently launched a type of inorganic waveplate (Nanoable® Waveplate) that functions to change the polarization state of light. With its excellent resistance to heat and light, Nanoable® Waveplate is even suitable for use with laser light sources.
Other new products under development include inorganic diffusers that can be used to control laser output patterns, and transparent conductive films that exhibit both low electric resistance and high transparency.

Our Nanoimprinting Technology
In film imprinting, a film substrate coated with a UV-cure resin is pressed against a patterned metal roll to form nanometer-sized structures (Fig. 2). The use of a roll-to-roll process results in high productivity.
We're working on imprinting with inorganic materials on glass substrates (glass imprinting) in the hope that nanoimprinted products could find use in a wider variety of applications. Because these products are made solely of inorganic materials, they can withstand light, heat, and chemicals much better than conventional film products. They are available in sizes up to 400 x 500 mm and can be manufactured in a continuous process based on roll-to-sheet technology.
