  • How Does an Optical Telescope Function?
    Article - 20 Jan 2022
    Optical telescopes concentrate light in the visible spectrum so that astronomers can look at objects millions of light-years away. This article looks at how optical telescopes work and their...
  • Benefits of Micro-Sized Cameras for Detecting Problems Inside the Body
    Article - 20 Dec 2021
    Researchers from the University of Washington and Princeton University have developed an ultra-compact camera the size of a coarse grain of salt that has surmounted micro-sized camera issues.
  • What is a Focal Point?
    Article - 5 Aug 2014
    A focal point is a common point on the principal axis where all the light rays starting from the object converge.
  • What is Transformation Optics?
    Article - 5 Feb 2024
