Optical Metrology

The founders and team members of TTI have a wealth of experience in the Photonics and Fiber Optics test and measurement industry dating back to the early 1970s when fiber was still in its infancy. After many years of ingenuity and dedication, we founded TTI in 1989 with the purpose of continuing to delight our customers, assist them in finding the best solutions, and keeping abreast of the technologies they deploy. Our roots may be in the Mohawk Valley Fiber Optic Industry of central New York, but our reach is global, and we pride ourselves in being a world class producer of the high tech solutions our customers require.
Our technology and product development experiences include design and marketing the world's first commercial processor driven Optical Time Domain Reflectometer. Other historic developments include Radiometric Energy and Power Meters, Optical Choppers, Space Probe Mission Sensors, and the industry standard Electrically Calibrated Pyroelectric Radiometer.
Over the decades we continued developing and refining our technologies with recent introductions in our full line of fiber optic test equipment including state of the art Optical Time Domain Reflectometers, hand held Optical Spectrum Analyzers, CWDM Channel Analyzers, Tunable Laser Sources and advanced autotest/autowave Loss Test Sets.
We also have a full line of optical to electrical converters, fiber optic links and a fiber optic video link system. We offer an optical chopper, laser power and energy meter, a fiber optic laser tachometer, photodiode transimpedance amplifier, and various other custom opto-electronic products that are utilized in the automotive, fiber optics, communications, photonics, power generation and medical equipment industries and for research laboratories, government entities and educational organizations worldwide.
Through our experiences the principle engineers at TTI are proud to have amassed over 100 years of combined experience in photonics and fiber optic instrumentation. We also are extremely proud to be one of the few USA developers and manufacturers of OTDRs and high tech photonics equipment, and look forward to maintaining this commitment.
In closing, we'd like to assure you that we are totally committed to our mission of providing leading world class quality solutions for our colleagues and friends. We maintain a passion for investments in our equipment designs, and development of exceptional customer relations through cooperation and training. We share this commitment in developing a superior TTI team through education, training and personal development.

Zygo Corporation is a global leader in the design and manufacture of advanced optical metrology systems and ultra-precise optical components and assemblies.
Our Metrology business segment is comprised of three major groups: optical surface profilers, laser interferometers, and stage position metrology. The products and systems produced by these groups employ various optical phase analysis techniques for measuring displacement, surface shape and texture, and film thickness. Applications for our metrology products are diverse, and include precision machining, optical manufacturing, and semiconductor manufacturing, as well as many others.
Our Optics business segment is comprised of two major groups: Electro-Optics and Optical Components. These groups leverage ZYGO's expertise in optical design and assembly, and high-volume manufacturing of precision optical components and systems, for aerospace, defense, medical, and industrial applications.
Recognized as a valued partner by its customers for innovative technology, application expertise, product reliability, and responsiveness, ZYGO leverages its differentiated core competencies in metrology and optics to assist these customers in becoming leaders in their respective markets.
Founded in 1970, and headquartered in Middlefield, Connecticut, USA, ZYGO's global operations are supported by approximately 500 dedicated and highly-skilled individuals around the world. Throughout its history, ZYGO has been driven by a passion for innovation, as evidenced by approximately 1,200 patents awarded since the Company's founding.
In 2014, ZYGO became part of the Ultra Precision Technologies Division of AMETEK, Inc., a leading global manufacturer of electronic instruments and electro-mechanical devices. With annual sales over $4 billion, AMETEK has more than 15,000 colleagues at nearly 150 operating locations, and a network of sales, service and support locations across the United States and in 30 other countries. ZYGO enjoys mutually-beneficial relationships with its AMETEK sister companies, collaborating on technologies and sharing resources in order to provide the best possible experience for our customers.
While we are a part of the AMETEK family, we are still the same Zygo Corporation that you have known and trusted for over 45 years, committed to serving your precision metrology and optics needs now and in the future.
