Abstract
An integral optical imaging device is disclosed in which two or more porous glass bodies, embodying arrays of cylindrical gradient index lens systems, are rigidly maintained in a stacked relationship such that the lens systems are in register. This enhances the accumulative lens power and effective thickness of the device.
