World’s thinnest lens developed


  1. News: Australian scientists have developed world’s thinnest lens which is 2000 times thinner than human hair
  2. Context: Newly developed lens is 6.3 nanometres thick. Previous versions of lenses were 50 nanometers thick
  3. Scientists have used a crystal of molybdenum disulphide as a special ingredient in this lens
  4. Applications: In medicine, science and technology and bendable tv and computer screens
  5. Properties: Single layers of molybdenum disulphide, 0.7 nanometers thick, had remarkable optical properties, appearing to a light beam to be 50 times thicker, at 38 nm
  6. This property, known as optical path length, determines phase of light and governs interference and diffraction of light as it propagates
