  11. “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.
