  • Curved optical device and method having a pair of opposed thermoplastic substrates with spacers therebetween to permanently retain a curved shape
    Patent number: 7705959
    Abstract: A curved optical device includes a pair of initially flat opposed flexible substrates that may have a fluid material with spacers disbursed therein disposed between the pair of substrates and sealed. The substrates have a uniform controlled distance therebetween. The substrates are permanently curved by applying heat and pressure with a mold while maintaining the controlled distance therebetween. The fluid material maybe a liquid crystal to provide the optical device with enhanced optical properties.
    Type: Grant
    Filed: July 14, 2006
    Date of Patent: April 27, 2010
    Assignee: AlphaMicron, Inc.
    Inventors: Yoan Kim, Roy Miller, Bahman Taheri
