Combines Vibration Insensitivity with Short Coherent Source
TUCSON, Ariz., Aug. 31, 2006 -- 4D Technology Corp., a manufacturer of dynamic laser interferometers, announces the introduction of its latest Fizeau instrument, the FizCam 2000. "This is a first-of-its-kind 'on-axis' vibration-insensitive Fizeau featuring a short coherence length source that enables measurement of transparent samples and assemblies which are difficult or impossible to measure with traditional laser interferometers," said James Millerd, 4D chief technology officer.

The short coherence feature of the FizCam 2000 eliminates the need for extraneous coatings to control these interfering fringes by isolating and measuring only the desired surface. In addition to measuring parallel optical grade surfaces, the FizCam 2000 is well suited for separating and measuring surfaces within an optical assembly, making remote cavity measurements, testing of index homogeneity, measuring thin optics and environmental chamber testing.

FizCam 2000 eliminates the need for bulky and slow phase shifters by incorporating a single camera, high-speed optical phase sensor that makes a wavefront measurement in as little as 30 microseconds. Because the acquisition time is so short, the FizCam 2000 can be used under almost any conditions, including measuring moving parts, without the need for additional isolation. Existing standard 4-in. Fizeau accessories from most manufactures are fully compatible with this system, so there in no need to replace costly components, 4D Technology said.

An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. Interferometers are used extensively for testing optical elements during manufacture. Typical designs include the Michelson, Twyman-Green and Fizeau interferometers. The basic interferometer components are a light source, a beamsplitter, a reference...
Pertaining to optics and the phenomena of light.
In considering a field of electromagnetic energy emanating from a source, the wavefront is a surface connecting all field points that are equidistant from the source.
