asphericon is the first company worldwide to use Tilted Wave Technology
Jena, December 2017:asphericon expands internal measuring technology with inauguration of the MarOpto TWI 60. The new interferometer is based on differently tilted wavefronts and evaluates aspheres and freeforms without computer-generated holograms (CGH). The main advantage lies in full-surface measurement within seconds with high lateral resolution and low measurement uncertainties – a quantum leap in metrology.
Producing optics of highest accuracy requires precise measuring technology. “I can only produce what I can measure,” emphasizes Sven Kiontke, CEO of asphericon. The company relies on a mix of tactile and optical methods and invests heavily in its own measuring technology. With the latest acquisition, the Tilted Wave Interferometer from Mahr, asphericon becomes a global pioneer. In contrast to existing systems, which require a measuring time of several minutes, the MarOpto TWI 60 makes it possible to measure entire surfaces in 20 to 30 seconds. “The time advantage is therefore significant,” emphasizes Dr. Ulrike Fuchs, head of applications at asphericon.
Faster, more flexible, more modern
Thanks to differently tilted wave fronts, TWI measures optics within a few seconds. Further novelty: already during evaluation of a test object the next one can be measured. In addition to the short measuring time, the MarOpto TWI 60 scores points for its flexibility. It is not only possible to measure aspheres but also optics with deviating geometries, so-called freeforms. The measuring instrument has such a robust design, it can be assembled directly in a production area.
Growing Machinery and Equipment Stock
With integration of the new device, asphericon expands its own range of measuring instruments. This is made possible by additional space gained this fall, within the asphericon campus in Jena. As a result of this expansion, the company has been equipped with the most modern measuring instruments in terms of depth and scope. In combination with the in-house database system, measurement results can be assigned to specific customer projects and thus enable evaluation and documentation that can be called up at any time.
