A GIANT Fresnel Lens EXPERIMENT | The Backyard Scientist

Get lost in the hypnotic optics of this sequence of photon micrographs, which show an array of Fresnel lenses, illuminated from behind. The lenses focused beams of light toward a camera. Using an optical microscope, our researchers took pictures of the array at different focus positions, moving from behind its glass surface to beyond the focused beams. Looping the micrographs together produced the mesmerizing result shown here. These microscopic versions of lighthouse lenses are useful in optica
