Meter Scale Optics Applications

Testing large optical components or complex optical systems is difficult with traditional phase measuring interferometers, due to vibration, air turbulence, and large standoff distances.

4D Technology’s PhaseCam dynamic laser interferometers make it easy to measure components that are mounted on separate, widely spaced, un-isolated optical tables, even in the presence of significant air turbulence. Remote operation, robust design quality and outstanding analysis software are built into every 4D system.

It's no wonder PhaseCams are used daily by some of the world's most prestigious manufacturers of large space-based and terrestrial optics.
