Abstract
A method of constructing a curved optical device includes assembling of at least one cell having opposed flexible substrates with a controlled distance therebetween to form a gap adapted to receive a fluid. The process continues by holding only a portion of the cell in a fixture, positioning a curved mold surface proximal the cell and heating at least one of the curved mold surface and cell. Next, the cell is conformed to the mold surface so that the cell substantially retains the curved shape when the heat and the mold surface are removed.
