Zygo Corp. announced it has received orders for metrology systems valued at more than $6 million from two Chinese optical research and manufacturing organizations. The orders were for large-aperture interferometers and associated reference optics that enable precise measurement of spherical optics greater than 12 inches in diameter. “Zygo’s China joint venture, headed by Dr. Lifeng Yin, continues to extend Zygo’s reach into this rapidly growing precision optics market,” said Don Battistoni, executive director of worldwide sales. “These specialized systems combine technologies from across our organization and expand our industry-standard interferometer product line to directly measure the full area of large spherical optics with high precision.” Zygo supplies optical metrology instruments, precision optics and electro-optical design and manufacturing services to the semiconductor capital equipment, biomedical, scientific and industrial markets.
