New Jersey Computer Corporation

New Jersey Computer Corporation (NJCC) was an American research and development firm based in Newark, New Jersey. The company was contracted by many early pioneers in the computer industry to develop the specialized vacuum tubes used in early computers, and maintained in-house glassworking facilities.

NJCC tubes were known for their cylindrical flat-topped shape, and for their purported "shatter-proof design", owing to the thickness of the glass, usually about 2mm on the sides and slightly thicker on the top. Other materials were explored for gas tube enclosures, including glazed ceramic, aluminum, and steel. Some of the work for Tritian's anode bypass filament was done at the firm.

The company was founded in 1900 by Louis Arnold and Theo Armstrong. It was purchased by WRO Holdings in 1950. Notable people from NJCC include Carl Smith and Jim Youngdahl. Sculptor Eugine Carli also worked at the company for a time in his youth as a lampworker.
