Technologies

asphericon-Technology-topDriven by the idea of developing new technologies and optimizing existing ones, we are continuously refining and improving our processes. In doing so, we strive constantly to achieve better quality and ever greater precision – without ever losing sight of our customers’ economic interests.

A unique technology to simulate CNC grinding and polishing processes, specifically developed by asphericon, enables the utmost precision on your aspheric surfaces. In comparison to standard processes, the asphericon technology works up to 75% faster and masters almost any shape and size.

In addition, all production parameters are recorded for each project and saved in an internal database system. This guarantees the traceability of all process steps and reproducibility at any time.

Leading by pioneering technology

Individual solutions at the highest level: Our patented technology to control CNC grinding and polishing machines with the ability to simulate processing methods, specifically developed by asphericon, forms the basis for our manufacturing. Thanks to this unique equipment, prototypes and high volume production can be manufactured with a high level of precision and can optionally be measured interferometrically over their entire surface.

Precision re-defined

Diamond-turned optics in perfection: Ultra precise cutting by using monocrystalline diamond tools is the key technology for manufacturing virtually any optical functional surface with the utmost precision. This allows the processing of non-ferrous metals, nickel-phosphorus coatings, plastics, crystals and IR lenses.

Exceeding standards

Precise for the highest demands: challenging optical applications demand ever greater surface form precision. asphericon delivers the required finish for your high-end products.

With asphericon ION-FinishTM and Magnetorheological Finishing-Technology® (MRF), it is now possible to process challenging aspheric optics in serial production for the first time. Thanks to this procedure, shape deviations are achieved that significantly exceed the current international standard.

If every photon counts or high laser output is involved, scattered light should not be an issue thanks to the novel asphericon Ångström-Polishing, which enables roughness values of 5 Å (Rq according to ISO 10110) to be achieved on all aspheric surfaces.

Equipment:

  • Ultra-precise ION-Scan 800 for waver-based coating thickness and frequency trimming
  • QED Q-flex series – magnetorheological polishing of various materials

Measuring

Measuring of aspheric surfacesThe most accurate measurement results from the specialist

The latest tactile and interferometric measuring instruments allow the flexible manufacturing of aspheric optics at the highest technological level. A specially developed and integrated database system enables measurement results from all manufacturing steps to be documented, evaluated precisely, and accessed at any time. A wide range of measuring instruments is used to achieve accurate measuring results.

Our experienced team is looking forward to your project!
