/keuh luy"deuh skohp'/, n.1. an optical instrument in which bits of glass, held loosely at the end of a rotating tube, are shown in continually changing symmetrical forms by reflection in two or more mirrors set at angles to each other.2. a continually changing pattern of shapes and colors.3. a continually shifting pattern, scene, or the like: The 1920s were a kaleidoscope of fads and fashions.[1817; < Gk kal(ós) beautiful + eîdo(s) shape + -SCOPE]
* * *Optical device consisting of mirrors that reflect images of bits of coloured glass or other objects in a symmetrical geometric design through a viewer.The design may be changed endlessly by rotating the section containing the loose fragments. A simple kaleidoscope consists of two thin, wedge-shaped mirror strips touching along a common edge. The mirrors are enclosed in a tube with a viewing eyehole at one end. At the other end is a thin, flat box that can be rotated; it is made from two glass disks, the outer one ground to act as a diffusing screen. In this box are pieces of coloured glass, beads, etc. When the box is turned, the objects inside tumble into an arbitrary grouping, and when the diffusing screen is illuminated, the sixfold or eightfold multiplication creates a striking symmetrical pattern. The kaleidoscope was invented by Sir David Brewster с 1816.
* * *▪ optical deviceoptical device consisting of mirrors (mirror) that reflect images of bits of coloured glass in a symmetrical geometric design through a viewer. The design may be changed endlessly by rotating the section containing the loose fragments. The name is derived from the Greek words kalos (“beautiful”), eïdos (“form”), and skopeïn (“to view”).The kaleidoscope was invented by Sir David Brewster (Brewster, Sir David) about 1816 and patented in 1817. Sold usually as a toy, the kaleidoscope also has value for the pattern designer.The kaleidoscope illustrates the image-forming properties of combined, inclined mirrors. If an object is placed between two mirrors inclined at right angles, an image is formed in each mirror. Each of these mirror images is in turn reflected in the other mirror, forming the appearance of four symmetrically placed objects. If the mirrors are inclined at 60°, a hexagonally symmetrical pattern results from one object producing six regularly placed images.A simple kaleidoscope consists of two thin, wedge-shaped mirror strips touching along a common edge or of a single sheet of bright aluminum bent to an angle of 60° or 45°. The mirrors are enclosed in a tube with a viewing eyehole at one end. At the other end is a thin, flat box that can be rotated; it is made from two glass disks, the outer one ground to act as a diffusing screen. In this box are pieces of coloured glass, tinsel, or beads. When the box is turned or tapped, the objects inside tumble into an arbitrary grouping, and when the diffusing screen is illuminated, the sixfold or eightfold multiplication creates a striking symmetrical pattern. The number of combinations and patterns is effectively without limit.Some kaleidoscopes dispense with the object box and use a lens to throw images of distant objects on the mirrors, an eyepiece at the viewing eyehole then being an advantage.
