| Research Abstract |
Glass lens and micro diffraction element are widely used in optical equipment, like digital camera, spectroscope and so on. In order to fabricate these kinds of optical elements with surface microstructures precisely and efficiently, glass molding press (GMP)is proposed to generate microstructures in this research. The following research result and achievement are obtained in these two years.
(1)Parallel microgrooves with a minimum pitch of 500 nm are created on the Nickel Phosphorus (Ni-P)surface.
(2)The forming condition for creating microgrooves on glass is optimized by Finite Element Method simulation.
(3)The experiments of glass molding press were carried out, and sub-wave-length optical diffraction element is successfully generated.
