PhaseCam 6110

Highest performance interferometer. Patented, vibration-insensitive measurement.

The new PhaseCam 6110 features a 4MP high resolution sensor, and a 2X improvement in both RMS repeatability and precision.

4D Technology PhaseCam 6110 High Performance Dynamic Twyman Green Laser Interferometer

The PhaseCam® 6110 is a compact, lightweight interferometer featuring patented Dynamic Interferometry and fully on-axis design. The measurement head is only 13 inches in length, with a high resolution 4MP imaging sensor, and a 2X improvement in both RMS repeatability and precision over its predecessor (the PhaseCam 6100).

The new PhaseCam 6110 features fully motorized controls, making it ideal for measuring large telescope optics, long path measurements, remote mounting in measurement towers or pressure vessels, and noisy or vibration-prone environments.

Dynamic Interferometry® technology enables the PhaseCam to make measurements in less than 30 microseconds—over 5000 times faster than a temporal phase shifting interferometer. Because it’s so fast, the PhaseCam can be used under almost any conditions—without vibration isolation—making it ideal for use on the production floor, in clean rooms and in
environmental test chambers, for measuring concave telescope mirrors and lens systems, as well as deformable mirrors and adaptive optics.

Numerous accessories and options are available including a 5-axis mount, low-reflectivity diverging lenses and beam expanders. A high-power 532nm external source for ESPI (Electronic Speckle Pattern Interferometry) is also available.


Demonstration of Measuring Large Optics Easily

This 4 minute video shows how easy it is to measure large optics using dynamic interferometers that are light, small and easy to align.

“It is such a pleasure using the 4D Technology machine (The Ferrari of interferometers).

Thank you for supplying us with such a great product.”
