Investigation of Diffractive Structure Designs through Printoptical® Technology


A next research has been recently published on realizing diffractive optics structures for various application areas such as in reality displays, integrated circuits and illumination. The current advancement in additive manufacturing allows rapid prototyping of diffractive structures at low cost within short time and little material waste. Here, diffractive grating with ridge width of 95 µm and diffractive lens with height of < 500 µm is fabricated with a good enough optical performance using Printoptical® Technology.
