Abstract
A photosensitive semi-conductor device is disclosed having a matrix of non-translucent dots on its photosensitive surface. In an array of photosensitive semi-conductor devices, such as photodiodes, the non-translucent dot pattern applied to this photosensitive surface of each photodiode is used to regulate the output from each photodiode. The dot matrix is preferably sputtered onto the anti-reflection coating of the photosensitive surface of the photodiode.
