Custom PhaseCam

Twyman-Green interferometers with custom wavelengths, multiple wavelengths, and other features

With super-fast acquisition speeds to as low as 30 microseconds and robust acquisition and analysis software, PhaseCam Twyman-Green interferometers are a superb platform to build a customized metrology instrument on. As a metrology company with a custom engineering group, we’re obsessed with solving problems for your applications.

PhaseCam® dynamic Twyman-Green interferometers are extremely compact and lightweight, with a wide range of wavelengths, camera options and features to serve most common optical measurement applications.

If your application requires a unique wavelength, multiple wavelengths, or features not found on our standard products, use the contact form at the bottom of this page—we would be glad to talk with you about developing a custom system that is tailored to your specific requirements.

Highlighted Features

Vibration insensitive

30 microsecond data acquisition time means you can measure in the most challenging environments

Compact and Lightweight

Designed with performance and remote measurement in mind. The small, lightweight systems are easy to mount, easy to move, and require less support structure.


The light-efficient system makes it possible to measure surfaces with reflectivity from 1% to 100%. Choose from measurement wavelengths from visible through infrared.


With acquisition speeds as fast as 30 microseconds, PhaseCam is over 5000 times faster than a temporal phase shifting interferometer, stopping vibration blur in its tracks.

Complete system

Includes all you need to take and analyse measurements. Choose from numerous accessories and options from the complete PhaseCam product line.
