Carl Zeiss doesn't have Bette Davis eyes, but it does make products that enhance visibility. Microscopes, planetarium projectors, and camera lenses are part of a portfolio that make the company a leader in optical and optoelectronic manufacturing. It operates in more than 30 countries through five business groups -- Semiconductor Manufacturing Technology, Medical Technology, Microscopy, Industrial Metrology, and Consumer Optics/Optronics -- and a joint venture called Carl Zeiss Vision, the #2 global leader in eyeglass lenses. Its production facilities are located in Europe, North America, Central America, and Asia. Carl Zeiss is a subsidiary of Carl-Zeiss-Stiftung (Carl Zeiss Foundation).
