The FizCam 2000 Fizeau laser interferometer combines vibration insensitivity and instantaneous phase measurement for highly accurate characterization of telescope and general-purpose optics.
FizCam 2000 dynamic laser interferometers simultaneously capture four phase-shifted interference patterns, allowing high-resolution measurement despite vibration and air turbulence.
The FizCam 2000 12-inch (300 mm) aperture system is ideal for measurement of large diameter flats. An optional extended path-matching feature enables cavity lengths to 2 meters.
The FizCam 2000’s proprietary laser source enables measurements which would otherwise be difficult or impossible, such as measurement of thin, plane parallel glass. The system can also measure “remote cavities,” in which both the test and reference surfaces are physically separated from the interferometer, as when measuring large telescope and satellite optics.
12-inch Tip/Tilt mounts for the reference and test optics are also available (shown below).
