Spherical optics with sizes 0.2 to 10.0mm are produced in following production types: single part production, small batch series and mass production. Surface form deviation can be measured and documented.
Spherical optics with sizes >10.0 to 20.0mm are produced in following production types: single part production, small batch series and mass production. Surface form deviation can be measured and partly documented.
Spherical optics with sizes >20.0 to 30.0mm are produced in following production types: single part production, small batch series. Surface form deviation can be measured and partly documented.
Plano optics with sizes 0.2 to 10.0mm are produced in following production types: single part production, small batch series and mass production. Surface form deviation can be measured and documented.

普莱诺光学与大小> 100.0毫米are produced in following production types: single part production, small batch series. Surface form deviation can be measured partly and partly documented.
Optomechanical assemblies are e.g. objective lenses built in a holder: There are no general tolerances available because each single assembly of these interdisciplinary products are worked out individually.
Development and production of a miniaturized camera with maximum resolution and flexibility. The dimensions of the components that enter the body are said to be as low as possible in order to shorten the healing process and to ensure the accessibility to the smallest vessels.
With the definition of the image sensor a big part of the requirements in the miniaturized camera already were transmitted:
With the development and production of this miniaturised camera was shown, that very small construction size (ø1.55 x 2.5) are sufficient to view and evaluate the picture of hard-to-access areas on a display screen – whether inside the human body or in a non-human cavity.
Demands of surgery:
Violations of the eye need to be kept very low during surgical interventions. Therefore, focus of development is on the size of instruments – the smaller the better.
Two important demands:
By means of delivered informations, a feasibility study with different optical concepts was worked out to evaluate advantages and disadvantages referring production, assembly and service at a very early time.
The specifications were defined after choosing the best concept.
With this optic of ophthalmic endoscope a new scale of rod lenses has been achieved. This optic defi nes proverbial the core of the smallest endoscope.
All parts (about 70) are optically contacted (contact blocked). Cements are inappropriate for assembly because the whole Image Slicer gets cooled down to 77K during application. The cooling-down is also the reason why material needs to have zero thermal expansion: Zerodur was choosen for all parts.
At the end, the surfaces are coated with gold.In total, 17 different small Slicer were manufactured. Each Slicer features a Wall- and Absolut- angle. The refl ecting surfaces stands skewed referring to entering beam path.
