APQ Design
Our aim is to offer our customers products with exceptional performance and distinctive features while maintaining the highest possible quality.
To set new standards in the development of optical systems and instruments, we work with internationally recognized experts who have many years of experience in optical and mechanical design.
Our principal design guidelines are:
Form follows function (Bauhaus)
Optical design
3D CAD
Finite element analysis (FEA)
Use of high-quality materials
- Optical Design
- Compensation
We believe that the latest CMOS sensors require innovative optical designs capable of meeting increasingly demanding image-quality requirements.
Visual observers also benefit from the newly developed Fluorite Quadruplet Polychromats: unlike most apochromats, their Strehl ratio does not fall toward or below the diffraction limit at the edges of the visual spectrum.
The optical design of our new astronomical objectives is presented in detail below. It was developed by Uwe Laux, Dipl.-Ing. (FH) in Technical Optics (for details, see Laux, Uwe: Astrooptik. Optik-Systeme für die Astronomie. 3rd revised and amended edition, 2017, pp. 146-155 and the related patent application).

To ensure thermal invariance, zero play and high centering accuracy, we developed a thermally compensated optical lens cell (compensation cell) for our Fluorite Quadruplet Polychromats.
The new compensation cell is designed for an operating temperature range from -20 °C to 40 °C (working temperature interval ≥ 60 K) and a storage and transport range from -40 °C to 60 °C.
The design of the cell assembly is outlined below. It was developed by Frank Dionies, Dipl.-Ing. (FH), with technical advice from Prof. Dr.-Ing. Manfred Steinbach (see also the related patent application).
