Teledyne Technologies Inc. closed on Tuesday its acquisition of the scientific imaging businesses of Roper Technologies Inc. The Thousand Oaks aerospace, marine and digital imaging products manufacturer will pay about $225 million in cash for the assets of Roper, in Sarasota, Fla. Roper’s scientific imaging businesses include Princeton Instruments and Photometrics, which makes cameras and optics for physical and life sciences research; and Lumenera, which makes rugged customized cameras for traffic management and life sciences applications. “These businesses have similar capabilities and are highly complementary to Teledyne’s products and markets,” Executive Chairman Robert Mehrabian said in a statement. Shares of Teledyne (TDY) closed Tuesday up $1.27 cents, or less than 1 percent, to $226.88 on the New York Stock Exchange.
