High‐Precision Printing of Complex Glass Imaging Optics with Precondensed Liquid Silica Resin (Adv. Sci. 18/2022)

3D Printing of Glass Imaging Optics In article number 2105595, Douglas A. Loy, Rongguang Liang, and co‐workers develop a liquid silica resin (the left molecule in the picture) to print optical element with high precision through two‐photon polymerization. The printed optics is then converted to inorganic glass (silicon dioxide, the right molecule in the picture) through thermal treatment. Precision complex glass optical systems, such as micro‐objective (in the picture), can be fabricated. This research demonstrates that 3D printing of glass imaging optics has a high potential for precision optical imaging applications. [Image: see text]
