On behalf of the EU and the German federal state of Schleswig-Holstein, Reinhard Meyer, Minister for Economic Affairs, Employment, Transport and Technology, presents the grant notification for the development of a new wave front sensor to Trioptics GmbH, a leading manufacturer of optical testing instruments.
As part of a project entitled “MEMS Wave Front Sensor for the Characterization of Optical Components – WaveScan“, Trioptics GmbH will be developing a next-generation wave front sensor. The company will be supported by the state’s economic program with funding from the European Regional Development Fund (ERDF). On the occasion of this decision, Schleswig-Holstein’s Minister for Economic Affairs, Reinhard Meyer, was pleased to present the grant notification personally at the company’s headquarters in Wedel.
“It has been excellent to learn that the importance of our project is shared by the state of Schleswig-Holstein and the EU,” says Trioptics Project Manager Dr. Florian Mathieu. Dr. Aiko Ruprecht, Manager of Advance Development, confirms this view: “We expect this project to show a solution for circumventing the limitations of current Shack-Hartmann sensors.“ Specifically, the goal of the project is to increase the dynamic area of wave front measurements based on current MEMS technology – miniature assemblies in the micrometer range in order to meet increasingly demanding requirements. This is especially true for the lenses used as intraocular lenses and contact lenses in ophthalmology and in endoscopes in medical technology. “This fulfils the requirements for measuring technology which has to measure the characteristics of highly complex lenses for quality control purposes after manufacturing,” Meyer says.
About current technology:
Wave front sensors can be used for the detailed characterization of single lenses and lens systems. The most commonly used type of wave front sensors are Shack-Hartmann sensors. In simple terms, a Shack-Hartmann sensor consists of a plane matrix of a large number of micro lenses that focus the incoming light onto a CCD or CMOS sensor, generating a characteristic spot pattern. Image processing can be used to reconstruct the wave front from the spot pattern and compare it to the theoretical design of the lenses. Inherent to their functional principle, Shack-Hartmann sensors are limited with regard to lateral resolution and dynamics, so that steep gradients and severe curvatures of a wave front can only be measured up to a certain limit.
