Sorry, this product is no longer available. A fun way to experiment with light diffraction! Lenses feature a computer-generated diffraction grating pattern with a seemingly chaotic mix of curved lines branching in and out of each other. The pattern takes advantage of nodes and antinodes caused by diffraction and assures that the gratings can take point light sources and bend or shift their light into a specific design. Activities include observing the diffraction pattern of point light sources (like Christmas lights), viewing lenses under a microscope to find the grating pattern, or shining a laser through the glasses onto a wall or screen. The pattern shines on the wall in the same way that the nodes and antinodes were displayed on the wall with the regular diffraction grating. Glasses measure 17 in. L x 2-1/2 in. W. Designs are assorted and colors are not guaranteed.
