“Mirage” History
The “Mirage” idea came from a chance observation of an image formed by World War II surplus searchlight mirrors stacked in a closet at the UC Santa Barbara Physics Department.
It was patented in 1972 by Caliste Landry and Virgil Elings (founder of Digital Instruments, Inc).
This patent transferred to Michael Levin in 1977.
Levin's company Opti-Gone International has made over 500,000 units to date.
A very large “Mirage” (22 inch diameter ) is also available.
