From ancient theories of vision to modern-day fiber optics and lasers, optical innovations have transformed science, medicine, art, and even everyday life.
In this video, we’ll take you on a journey through time, starting with Alhazen, the "Father of Optics," whose groundbreaking theories on light and vision laid the foundation for modern optical science. We'll explore how his ideas influenced the medieval scholar Roger Bacon, who advocated for experimentation and helped pave the way for corrective lenses in Europe.
Next, meet Hans and Zacharias Janssen, the father-son duo credited with inventing the first compound microscope, which unlocked the microscopic world and revolutionized biology and medicine. We’ll also introduce you to Hans Lippershey, the Dutch spectacle maker who gave us the first practical telescope, and Galileo Galilei, who took Lippershey’s invention to new heights, altering our understanding of the cosmos forever.
Antonie van Leeuwenhoek’s meticulous lens crafting led to the discovery of bacteria and the birth of microbiology. In the world of photography, Joseph Nicéphore Niépce and Louis Daguerre created the first permanent photographs, changing how we capture and preserve moments.
We’ll also delve into the medical advancements driven by Hermann von Helmholtz, whose invention of the ophthalmoscope revolutionized eye care. Then, learn about the development of the electron microscope by Ernst Ruska and Max Knoll, which allowed scientists to observe the world at the atomic level. And don’t miss the story of Harold Hopkins and the invention of fiber optics, which transformed telecommunications and medical imaging.
Finally, we explore the invention of the laser in 1960, a breakthrough that has since become integral in countless fields, from surgery to industrial applications, and the advancements in optical lenses that shaped modern photography and cinematography.
