Microlens Arrays from a Test Tube

Facebook X LinkedIn Email
POTSDAM, Germany, March 22, 2012 — Simple calcium carbonate precipitation at ambient conditions can produce microlens arrays of uniform size and focal length. This process offers a cheaper alternative to lithographic techniques used to create inorganic-based materials. Scientists at the Max Planck Institute of Colloids and Interfaces collaborated with researchers from the University of Konstanz, the Korea Institute of Geoscience and Mineral Resources, and the KAIST in South Korea to develop the optically functional micrometer-sized hemispherical CaCO3 structures. To create the microarrays by simple mineral precipitation,...Read full article

    micro-optics
    Micro-optics refers to the design, fabrication, and application of optical components and systems at a microscale level. These components are miniaturized optical elements that manipulate light at a microscopic level, providing functionalities such as focusing, collimating, splitting, and shaping light beams. Micro-optics play a crucial role in various fields, including telecommunications, imaging systems, medical devices, sensors, and consumer electronics. Key points about micro-optics: ...
