The round, colored picture is a sample of the "view". Keep in mind that a kaleidoscope "view" is moving so the sample is a "stop-frame" of a view and is only representative of the moving colors.
FRONT SURFACE MIRRORS & KALEIDOSCOPES
When an ordinary mirror is used in a kaleidoscope, light must pass through a layer of glass before being reflected by the silvering on the back of the mirror. Since glass is not perfectly clear or perfectly flat, some attenuation of the image results, along with “ghost images” caused by reflection off of the surface of the glass. These undesirable effects are compounded in a kaleidoscope mirror assembly and cause the viewing field’s outermost edges to dim, blur, and become full of interference lines.
By using aluminized front surface mirrors these problems are solved. Front surface mirror is made by vacuum depositing a highly reflective aluminum surface coating onto the FRONT of the glass. The light then reflects off the aluminized coating and does not pass through the glass. The high reflectivity (approximately 95%) and the absence of ghost images permits a brilliant image which remains clear and bright throughout the viewing field. The resulting “hall of mirrors” effect results in images and colors that are much sharper and more intense than would be possible using ordinary mirror.
The kaleidoscope is 10" long and 2 1/4" wide.
