Abstract
A small, low cost, solid state camera is achieved by the placement of the requisite molecular sieve in a chamber separate from the vacuum chamber which houses the solid state device (CCD). The sieve chamber is connected by a narrow tube to the vacuum chamber and functions as a passive pump. The sieve chamber has a removable cover which permits replacement of the sieve after manufacture.
