Matthew Dubin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical devices employing beam folding with polarizing splitters
    Patent number: 6597504
    Abstract: A beam folder increases optical length with polarizing beam splitters and reflectors that repolarize a beam by retarding it. An incident beam encounters the beam splitters multiple times, and are both passed and rejected by the same splitters. The splitters and repolarizing reflectors can be shaped to perform optical functions in a smaller volume. Valves and controls can vary the beam intensity and combine multiple beams. Applications include projection, imaging, collimating, mixing, and balancing.
    Type: Grant
