![]() The images created are striped patterns since the reflections move directionally up, down, left and right. These are created by angling the 4 mirrors at 90 degrees to each other. The square and rectangular configurations create basically the same pattern except the square 4-mirror configuration (shown above) produces repeated square patterns while 4-mirror rectangular configuration produces repeated rectangular patterns. They come in three common configurations: The 4-mirror system is created when 4 mirrors are connected together. Notice that the last scope is a view of the mirrors after the wheels were removed (the second photo shows the 30-60-90 scope's mirror system up close).īelow are the images from the 3 scopes (order - equilateral triangle, isosceles triangle and the 30-60-90 triangle). The Isosceles Triangle (has two equal sides)Įach of these images would be repeated throughout the entire field of view.īelow are examples of the three most popular types of 3-mirror systems (the 60-60-60 equilateral triangle, the isosceles triangle and the 30-60-90 triangle).There are four comon configurations of 3-mirror systems in order of popularity: With this system, images are reflected throughout the entire field of view producing honeycomb-like patterns. The 3-mirror system is configured in a triangular shape. Notice the half point on the bottom of the center picture. The mirror angles are at 36 degrees (5 points), 33 degrees (5.5 points) and 30 degrees (6 points). If the angle doesn't divide evenly into 360, for example 50 degrees (360 / 50 = 7.2), it will produce a non-symmetric pattern.īelow are three pictures of the same image inside the same scope. The image created by a 2-mirror system will be symmetrical if the mirror angle is an even divider of 360 degrees. Here are the calculations for the common angles used with 2-mirror systems: Angle of Mirrors Points = 180 divided by the angle of the 2 mirrors.Folds = 360 didided by the angle of the 2 mirrors.The following mathmatical formulars will calculate he number of folds and points: ![]() An image circul with 5 points will have 10 folds or reflections. The tighter the angle the higher the number of reflections (called folds). The angle of the 2-mirrors determined the number of reflections that comprise the image circle. That central image is circular in shape and is a reflection of the objects being viewed. It produces one central image in the middle of the viewing field. Two sides are mirrors and the third side blackened. The 2-miiror system is configured in a triangular shape. For that reason many jewelry scopes utilize the spiral mirror system.īelow is a photo showing two jewelry scopes that utilize the spiral mirror system. The extremely small size of jewelry scopes makes it hard to create small enough mirror systems. While not often used in kaleidoscopes, you see it used more often in jewelry scopes (rings, necklaces and earrings). Objects in the object cell of these scopes are used more to create colors then shapes since all the viewer sees is a swirl of color coming towards them. This type of mirror system can also be called a 1-mirror system since only a single reflective material (mirror) is used.īelow are two images from the same spiral scope. The scope's cylinder shaped body or a cylinder tube inside the scope is covered with a reflective material which produces a spiraling effect of colors up toward the viewer. Here are some photos and videos of 3-D kaleidoscopes and there images from Janet & Frank Higgins (personal favorites are "St Basil 2010", "Super Carousel" and "Cube").
