    Kaleidoscopes use Mirrors

  1. Large kaleidoscope in San Diego

    A kaleidoscope is an enclosed tube that surrounds two or more mirrors placed at angles to each other. The angle and number of these mirrors will determine the image seen through the eye hole at one end. At the end piece of the kaleidoscope there can be a tube filled with colored particles, one or more colored wheels or a lens. When the end piece or the kaleidoscope is turned, the images seen inside are changed.
  2. Kaleidoscopes with Two Mirrors

    A kaleidoscope with two mirrors placed at an angle to each other will reflect the image in the end piece to create a circular image to the viewer. This pattern is set against a solid color background. An example can be seen in the image.
  4. Three Mirrors in a Kaleidoscope

  5. Endless array seen in kaleidoscope with three mirrors

    Three mirrors arranged in an equilateral triangle facing each other will produce a repeating pattern because the image is bouncing off of all three mirrors. This endless array does not have a definite border as two mirror images do.
  6. Four Mirrors in a Kaleidoscope

  7. Linear pattern seen in four mirror kaleidoscope

    When four mirrors are arranged in a square, the resulting image is a line of repeating images. This linear pattern results from the image evenly reflecting off of all of the mirrors.
  8. Twin Set of Two Mirrors

  9. Twin image seen in twin double mirror kaleidoscope

    Two sets of mirrors facing each other set at angles will create a double image. The light bounces off of these four mirrors at a sharper angle than the four mirrors set at 90-degree angles. The image is doubled rather than creating a repeating linear pattern.
