For now, Spectra-Physics Lasers (Mountain View, CA) will remain a public company, even though its parent firm Thermo Electron Corp. (Waltham, MA) is undergoing a major reorganization designed to refocus it on its core business of measurement and detection instruments. Thermo Electron will "continue to evaluate" the Spectra-Physics business, in which it acquired a major stake last year. Thermo Electron plans to split into three independent public entities. The core business, retaining the company name, will provide instruments for the life sciences, telecommunications, analytical, process control, laser, optical components, precision temperature control, and environmental monitoring markets. Two business to be spun off as dividends to the firm's shareholders include Thermo Fibertek, which focuses on separation technologies for the pulp and paper industries and fiber-based composite products, and a new medical products company that will combine several existing business units—Paula Noaker Powell
