Optical Devices/Optical Components
We develop nanoimprinting materials that can be used to form the structure of optical elements for AR/VR and 3D sensors.
The ultra-thin hydrophilic coating material with visible light transmission of ≈100% can be used as a functional coating that does not interfere with optical properties for transparent materials such as automobiles,
construction materials, glasses, goggles, and cameras.

Separation Membrane
We are developing porous polyimide films that can be used as separation membranes for next-generation batteries. Our porous polyimide film features extremely uniform pores, and is expected to be used for a wide range of other applications due to its high heat resistance, high chemical resistance, and low dielectric properties.
