High performance dynamic Twyman-Green laser interferometer

Flexible, vibration-insensitive, 4MP PhaseCam 6110.

The PhaseCam 6110 incorporates a 4MP sensor for high resolution measurement, with a 2X improvement in both RMS repeatability and precision over previous models. With an easy-to-position, fiber-coupled measurement head and motorized controls, it’s ideal for long path measurements, remote mounting, and other challenging test setups.

PhaseCam 6110 Description

The PhaseCam® 6110 is a compact and lightweight dynamic laser interferometer. The vibration-immune 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).

Operating at 633 nm wavelength, the PhaseCam 6100 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-rich environments.

The new PhaseCam 6110 incorporates Dynamic Interferometry® technology, using a single camera, high-speed optical phase sensor to make wavefront measurements in less than 30 microseconds—over 5000 times faster
than a temporal phase shifting interferometer. Because acquisition time is so short, the PhaseCam can be used under almost any conditions, without vibration isolation. Vibration immunity makes the PhaseCam ideally suited 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.

What to expect

Operating at 633 nm, the PhaseCam 6110 is a small aperture surface measuring and wavefront transmission measuring interferometer.

With super-fast acquisition times, it’s ideal for long optical-path measurement of large focal systems, as well as deformable mirrors and adaptive optics. It’s highly popular in measuring concave telescopes mirrors and lens systems. It’s also great for testing small aperture afocal components like flat mirrors and collimators.
