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," Zecchino says. "It's like watching Swiss
watchmakers; they do some incredible work."
