Teledyne Technologies is headquartered at this isolated campus in the hills of Thousand Oaks, which also serves as an R&D center for Teledyne’s Scientific and Imaging division. Founded by former Litton employees in Beverly Hills in 1960, Teledyne makes aerospace and defense electronics, and specializes in enhanced optics, multispectral detection, and digital imaging. Though it sold its Electronic Systems division to Litton in 1995, it still employs around 15,000 people, many of them in Southern California. Teledyne’s gated headquarters, at the end of a long driveway, now surrounded by an upscale housing development called Lynn Ranch, was originally built as a scientific research site by North American Aviation in 1962, and operated for decades as the Rockwell Science Center, after Rockwell acquired North American. Working primarily on government and defense projects, the lab made advances in ceramics, infrared imaging, LCDs, and other display and computing applications. Teledyne bought the site from Rockwell Scientific in 2006.
