4D 4D Technology’s handheld 4D InSpec® Surface Gauge fundamentally changes how precision surface measurement is accomplished, saving customers time and money. By Janice Hoppe-Spiers

4D Technology is known for its innovative design and manufacturing of metrology products for optics fabrication, astronomy, aerospace and other challenging applications. Dynamic Interferometry®, the technology behind many 4D products, ensures precise measurements in the most difficult environments without vibration isolation.

“We are a small and innovative company that has taken on measurement challenges that make projects such as space-based telescopes possible,” Marketing Communications Manager Mike Zecchino says. “We have been the company that’s taken on the real challenges and developed very many of the changes in the field of interferometry over the years.”

Founded in 2002, 4D’s patented technologies continue to set it apart from the competition. Built around proprietary phase sensors, 4D interferometers acquire high-resolution phase data and are insensitive to vibration and environmental noise. Dynamic Interferometry technology enables measurement of optical-grade surfaces in challenging environments, as well as high-resolution measurement of moving surfaces.

Many of 4D’s products originated from unique customer requirements that it turned into product lines to meet more customers’ needs. The company’s 45 employees are made up of mechanical, optical, electrical and software engineers, and the manufacturing team who build the instruments. “They are very specialized and do fantastic work,” Zecchino says. “It’s like watching Swiss watchmakers; they do some incredible work.”
