HOME > Reseach and Development Recently, plastic products have been rapidly evolving with increasing precision, and outperforming other materials. Based on our expertise with nanolevel mold-machining technology and nanolevel inspection, we are carrying out development of new products in the optoelectronics and biomedical fields. For the research and development of nano level technologies, Yoshikawa Kasei founded a Nanotechnology Center. Such leading-edge research and development efforts have been ensuring Yoshikawa Kasei's agility in designing and prototyping the optical mechanisms of high precision optical components and in shifting to mass production in a state-of-the-art clean room factory. Our know-how in plastic optical device manufacturing has always advanced with feedback from the design stage onward. That's why our process technology and seasoned development staff are able to take on unique challenges and succeed.
