ABSTRACT:
A digital imaging charge coupled device or CCD camera has a hollow camera body defining a sealable interior focal plane chamber enclosing a CCD array positioned to receive light focused thereon through a light-transparent window. The interior chamber also encloses a molecular sieve moisture adsorber of crystalline alumino-silicate material, and the chamber is evacuated, filled with inert nitrogen gas under slightly elevated pressure and then sealed, minimizing the partial pressures of water vapor or outgassing gases and reducing or eliminating their efforts on the CCD array.
