Zoom systems based on tunable lenses: a systematic first order design method

Leonhard Lenk, Beate Mitschunas, Stefan Sinzinger

Technische Universit├Ąt Ilmenau, Germany

Various authors have shown that tunable lenses, whose refractive power can be varied e.g. by changing the curvature of a membrane, can replace the motion of lens groups in zoom systems. As with classical zoom systems, the first order layout has a major influence on the performance of the final system and, moreover, sets the requirements for the tunable lenses. We present a method for the analysis of the vast number of possible first order solutions for typical requirements and for the selection of most promising layouts.

TOM 3 Optical System Design, Tolerancing and Manufacturing

High-resolution measurement technology for the detection of complex process influences in machining operations

Till-Hendrik Hage1, Marco Fritzsche2, Sebastian Henkel1, Jens Bliedtner1

1Ernst-Abbe University of Applied Sciences Jena; 2Polytec GmbH

The purpose of this paper is to discuss the influences of vibrations on the quality of the machining results, which are caused on the one hand by the operating vibrations generated by the running spindle and on the other hand by resonance frequencies. In order to detect these influences, a modal analysis and a measurement of the operational deflection shape are carried out on an ultrasonic-assisted CNC grinding machine designed for machining of brittle materials and on a 5-axis-CNC universal milling machine using a three-dimensional scanning Laser Doppler vibrometer system.

Systematical approach for deterministical Determiation of the laserpolishing processing window for new optical materials: smoothing and ablation

Jens Bliedtner, Oliver Faehnle, Kerstin Goetze, Anne-Marie Schwager

University of Alpplied Sciences Jena, Germany

Among the approximately 300 different processes for polishing high-performance optics, laser polishing is distinguished by the fact that it can be digitally controlled, does not introduce any contaminants, can process even the smallest concave radii of curvature without contact and it is extremely fast. Therefore, laser polishing is a promising polishing technology, which has not yet found its way into industrial application; this is mainly due to the complex process setup, where material-, laser- and engineering-technologies have to be combined on a high technology level.
