Zygo Corporation enhances industry-leading Verifire™ laser interferometers for improved performance and value

Verifire™ Interferometer System
MIDDLEFIELD, CT - Zygo Corporation is pleased to announce the latest addition to its industry-leading Verifire™ family of laser interferometer and optical testing products. Verifire laser interferometers employ advanced software and hardware technology to ensure precision metrology and characterization of optical components and systems in both manufacturing and laboratory environments.

Precision, Performance and Versatility

This latest addition to the Verifire line leverages ZYGO's nearly 45 years of experience in producing advanced metrology instruments. The system is configured with key capabilities that establish a robust, high-quality and flexible laser interferometer with a low cost of ownership. Its true Fizeau, on-axis optical system provides the basis for its high-accuracy metrology capabilities. Patented QPSI™ vibration-tolerant acquisition technology provides the instrument with its unique ability to obtain reliable measurements in production environments. At the core of the system is a proprietary, frequency-stabilized laser that delivers high output and life-long reliability - backed by a 3-year warranty - ensuring maximum up-time and dependability.

"The new Verifire interferometer represents additional value and lower cost of ownership for our customers" remarked Tyler Steele, Product Manager for Laser Interferometers at ZYGO. "With the enhanced capabilities, performance and warranty coverage of our standard entry-level system, we can now offer an extremely capable, well-equipped instrument at a more accessible price point for the industry."

The versatile Verifire product includes a continuously variable optical zoom that can be operated in horizontal or vertical configurations. The system is offered in various output beam aperture sizes and is supported by a full range of ZYGO manufactured and certified accessories.

"We are excited to offer our customers a high level of commitment and protection on their investment. We stand behind our products and plan to continue to innovate and lead the industry." said Tyler Steele, Product Manager for Laser Interferometers at ZYGO.

Enhanced Software and User Control

The new Verifire is controlled by ZYGO's powerful Mx™ software platform, which includes many new features for improved performance and usability, including SmartAveraging® and SmartRemote compatibilities. SmartAveraging is a software feature that optimizes measurement quality by automatically acquiring the appropriate number of averages required to ensure the desired level of certainty, minimizing operator variability. SmartRemote is a wireless hand-held device used to control the instrument, providing users with enhanced functionality, ease of use, and remote instrument operation.

Zygo Corporation, a unit of AMETEK Ultra Precision Technologies Division, is a leading provider of optical metrology solutions, high-precision optics, and optical assemblies used in a wide range of scientific, industrial, and medical applications.

AMETEK, Inc. is a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of $4.0 billion. For more information, contact ZYGO, 21 Laurel Brook Rd., Middlefield, CT 06455-1291 USA. Telephone: +1-860-347-8506. E-mail:
