FizCam 2000 12-Inch Short Coherence Interferometer

12 in aperture (300 mm) for large flats.

The FizCam 2000 12 inch aperture Fizeau laser interferometer combines vibration insensitivity and instantaneous phase measurement for highly accurate characterization of large optics including telescope lenses and mirrors.

Measure large, plane-parallel optics

The FizCam 2000 12 inch aperture Fizeau laser interferometer combines vibration insensitivity and instantaneous phase measurement for highly accurate characterization of large optics including telescope lenses and mirrors.

FizCam 2000 dynamic laser interferometers simultaneously capture all phase data simultaneously, allowing high-resolution measurement despite vibration and air turbulence. The  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 surfaces. 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.

Plane parallel surfaces

Short Coherence Fizeau for measuring parallel glass surfaces closer than 300  microns (µm), remote cavity measurement, and thin optics.

Vibration Insensitive

Measure despite vibration and environmental noise.

Mounts and Optics

Range of reference and return optics and mounts.

What to expect

The FizCam 2000 dynamic Fizeau interferometer is a new on-axis design providing high accuracy measurement of optical grade surfaces with almost complete insensitivity to vibration and air turbulence. The system enables measurement of large flats, including those with parallel surfaces, without the need for extraneous coatings to control multiple interference fringes.

The FizCam 2000 eliminates bulky and slow phase shifters by incorporating patented technology using a single camera, high-speed optical phase sensor that makes a wavefront measurement in as little as 30 microseconds. Because acquisition time is so short, the FizCam can be used under almost any conditions, even for measuring moving parts, without additional vibration isolation.

The short coherence length source allows for measurement of close (< 0.3 millimeters) parallel glass surfaces. Other applications include remote cavity measurement and measurement of thin optics.

The FizCam 2000 12-inch is sold as a turnkey interferometric system:

  1. Interferometer
  2. Advanced software for taking measurements and analyzing the results
  3. Complete computer system
  4. Connecting cables and power supplies

Accessories can include:

  • Optical mounts
  • Reference optics
  • Linear table guides.

4Sight™ wavefront analysis software, included with every AccuFiz, features excellent ease of use and a short learning curve. 2D and 3D displays, filtering, thresholds and masking tools make it easy to highlight surface shape and texture. Zernike, Seidel, geometric and diffraction analyses are easy to perform. Comprehensive data sharing capabilities let you read, write, save and print data in many common file formats for comparison between instruments. Optional 4Front™ software enables real-time measurement for system alignment, and fast averaging of many datasets.
