| Zusammenfassung: | A kaleidoscope includes three or four highly polished plain, front-surface mirrors assembled in the form of a prism with a cross section that is an equilateral triangle, a square or a rhombus with the angles between sides of 60 DEG and 120 DEG , having a length 8 to 15 times the linear dimensions of its cross section. An optically opaque cylinder encloses the mirror assembly with opaque end caps providing alignment of the positions for the ends of the mirrors and electric light means for illuminating objects being viewed. |
