Hyperlens Mass Production Incoming
[386호] 2017년 05월 24일 (수) Reporter Kang Min-Seok .
A joint research team of Professor Rho Jun-suk (ME, CE) and Lee Heon (Korea University) developed a new manufacturing process of hyperlens utilizing nanoimprinting lithography.
Optical microscopes cannot magnify a subject smaller than half of the wavelength of light ray because of diffraction limit. Unlike ordinary glass lenses, hyperlens is a lens that can overcome diffraction limit and allows observing smaller objects than the limit.
Hyperlens is expected to make a breakthrough in optical imaging, but its commercialization faced difficulty in manufacturing process. Cutting the surface of lens using thin ions or electron beam requires a lot of time and effort, which is not suitable for mass production of hyperlens with large area.
The research team proposed an innovative approach to the manufacturing process by creating a mold and printing the pattern like stamping. There were also difficulties in placing the sample exactly on the right position, which was one of the main reason that stopped the commercialization of hyperlens. The research team made a board with array of numerous hyperlenses to solve this problem.
Prof. Rho mentioned that “This research has its significance at confirming that hyperlens is possible to be utilized in various fields.”
