Magical Glass Technology: What other products use glass and how

The video explores the use of glass in space exploration and semiconductor industries. It highlights the Very Large Telescope at Mount Cerro Paranal, which uses advanced glass technology for astronomical observations. The video also discusses the role of glass in semiconductor development, focusing on optical lithography and the challenges posed by short wavelength light. Solutions such as calcium fluoride crystals are presented, which are used in high-resolution lenses for cameras and microscopes.
