Abstract
A barrier package for the storage of lens wafers used in fabricating laminated lenses, comprises a package adapted to be sealed to enclose therein a lens wafer and formed of a multilayer material, including a metallic layer, of low moisture transmission rate, so that conditions of humidity inside the sealed package are substantially isolated from humidity conditions external of the package. Lens wafers so stored exhibit minimum distortions to interface curvature. Instead of or in addition to being stored in a barrier package, the lens wafers can also be coated with a moisture barrier coating to achieve isolation from external humidity fluctuations. The moisture equilibrated precision lens wafers are suitable for use in optical devices.
