ZYGO has been manufacturing laser interferometers for 50 years, and specialize in Fizeau interferometers, characterized by ease-of-use, making them the go-to solution for extremely precise optical and engineering measurements. Our interferometers are the go-to alternative to contact probes, and are designed to increase quality and advance process automation and manufacturing efficiency, and use optimal laser technology that means we can measure distances to within 1 nanometer. Whether in the QC lab or for in-process measurement in the most violent or extreme conditions, anything is possible through the use of our unique and patented data acquisition technologies. Quality and process control are at the heart of our customers’ requirements, and today thousands of companies around the world use our reliable metrology tools backed by innovative algorithms to guarantee excellence in production measurements of surface form of components and assemblies.
