| Number | Title | Issue Date |
| 3992206 | Method of making lenticular surfaces Lenticules of predetermined optical power and size are formed photographically in the emulsion of a photographic film. An emulsion is exposed to a target having a profile mathematically related to the cross sections desired in the lenticules to be formed.... | 11/16/1976 |
| 3988153 | Method of forming a thin film iris diaphragm for a corpuscular beam apparatus A method of forming an iris diaphragm for use in a corpuscular beam apparatus and having a thin metal layer with at least one opening and an integral reinforcing portion of the same metal which is set back from each of the openings characterized by provid... | 10/26/1976 |
| 3961102 | Scanning electron microscope fabrication of optical gratings A method of making optical gratings by the use of a Scanning Electron Microscope wherein (1) a substrate having a thin film of electron resist thereon is exposed in adjacent areas by an electron dosage and the amount of such dosage and the depth of the th... | 06/01/1976 |
| 3953620 | Producing integrated optical circuits A technique for the fabrication of integrated optical circuits is described wherein a transparent polymer film, which is doped with a polynuclear aromatic thiol having higher index of refraction than the polymer, is deposited from a liquid solution on a s... | 04/27/1976 |
| 3948660 | Method for the manufacture of fresnel lenses using light-sensitive materials In a method of forming a Fresnel lens from a body of light-sensitive material of the type which undergoes changes in its optical path-length when exposed to light, the step of exposing each portion of such body of light-sensitive material to light to the ... | 04/06/1976 |
| 3934057 | High sensitivity positive resist layers and mask formation process A high sensitivity resist layer structure for high energy radiation exposure is formed by coating plural layers of radiation degradable polymers on a substrate which layers are successively slower dissolving in the resist developer. Upon exposure and solv... | 01/20/1976 |
| 3932184 | Fabrication of microlenses Photolithographic techniques are employed to fabricate hemispherical or semicylindrical microlenses on the end surfaces of optical fibers. The power coupling efficiency between junction lasers and fibers is thereby significantly increased.... | 01/13/1976 |
