  • Microform reader
    Patent number: 4126387
    Abstract: A pocket-sized microform reader is realized by employing a unique lenticular (screen) assembly and a projection lens assembly, the latter permitting a fold in the middle of an optical path allowing the size requirements of such a reader to be met. The cooperation between the lenticular screen and the projection lens assemblies permits sufficient brightness to be obtained and the lenticular screen assembly defines a non wasteful exit pupil of limited dimensions consistent with a pocket-sized reader.
