Tucson, AZ, April 9, 2014 – 4D Technology has introduced a suite of products for high quality, low cost measurement of 300mm diameter optics.

"Our goal was to create a measurement system for large optics with the performance, flexibility and value of our standard systems," said James Millerd, President of 4D Technology. "We designed the system around a standard, 100mm aperture AccuFiz® interferometer to take advantage of its high wavefront quality and reliability. We then developed a series of precision components which enable measurement of large afocal optics and large diameter curved surfaces (using CGH null optics), as well as the entire range of optics that can be measured with the standard AccuFiz in stand-alone mode."

The suite of 300mm components includes a compact, high performance 100–300mm Beam Expander which can be used in horizontal or look-down measurement configurations. Kinematic mounting makes it possible to quickly remove the AccuFiz for free-standing operation, then to return it to the beam expander with no need for re-alignment. A visible coarse alignment laser is also available to quickly position the reference and test optics for rapid test setup. The new 300mm Rotational Mounts provide highly repeatable tip, tilt and rotation control of the test and reference optics. Precise adjustments enable 3-Flat Testing when extremely high accuracy measurement is required. The External Phase Shifting Mount adds the ability to measure in remote cavity setups.

All components were optimized for the AccuFiz but can also be adapted for use with other manufacturers' 100mm aperture interferometers.
