QED Implements ASI Metrology System

QED Technologies, a magnetorheological finishing (MRF) and subaperture stitching interferometry (SSI) instrumentation provider, announced that one of its new aspheric stitching interferometers (ASI) has been installed at the Leibniz Institute for Surface Modification (IOM) in Leipzig, Germany.

The ASI is part of the company’s newest line of full aperture metrology systems. Capable of measuring steep aspheres with as much as 1000 waves of departure, it operates without the use of dedicated null lenses or computer-generated holograms. It significantly reduces the cost and lead time for producing aspheres compared to traditional methods, said the company.

The addition of the ASI will enable IOM to develop surface figuring and finishing steps that produce surfaces with accuracies in the nanometer range. It will be utilized specifically for precision fabrication and measurement of aspheres.

With more than 20 years of experience in the development of advanced subaperture surface figuring technologies, IOM has made significant investments in state-of-the-art surface machining and metrology equipment to support its work in surface and thin film modification.
