Kaleidoscope history and design,19th-century diagrams. Kaleidoscopes contain coloured glass beads and mirrors that create patterns. At top is a piece of glass cut for use in a kaleidoscope. Below that is a kaleidoscope projector. At lower right is an image multiplied using a kaleidoscope. Early attempts at mirror devices are at left and right by German scholar Athanasius Kircher (c.1601–1680) and British botanist Richard Bradley (1688-1732). An optical effect noticed by Bradley is at lower left. These diagrams are from 'A Treatise on the Kaleidoscope' (1819) by Scottish physicist David Brewster (1781-1868). Brewster patented his kaleidoscope invention in 1816 | |
