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 may be a liquid crystal to provide the optical device with enhanced optical properties.
