QED Technologies announces implementation of its ASI Metrology System
The ASI operates without the use of dedicated null lenses or computer-generated holograms, significantly reducing the cost and lead time for producing aspheres compared to traditional methods. Aspheres are increasingly used in precision optical systems, since the use of aspheres generally results in fewer optical elements, less weight and reduced size, thereby simplifying and reducing the cost of optical systems.
IOM is a leader in its field, with more than 20 years of experience in the development of advanced sub-aperture surface figuring technologies. Recently, 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. The ASI is an important addition to the IOM facility, enabling IOM to develop surface figuring and finishing steps that produce surfaces with accuracies in the nanometer range. The ASI is intended to be used by IOM specifically for precision fabrication and measurement of aspheres.
“At IOM, we put a strong emphasis on collaboration with industry, universities and other research institutes to develop new applications for the optical and semiconductor industries. With its unique performance and advanced features, we see the ASI as a key component to our research and development efforts,” said Thomas Arnold, PhD, Leader of the Young Researchers Group of the IOM.
