Increasing demands in imaging quality of all assembled optical systems require the optimization of lateral and axial alignment of individual lenses. An economic possibility to improve mechanical alignment is the step-by-step centration testing of the

Thanks to their size and weight reduction and error correction potential, aspheric designs are seeing an industry-wide adoption. This not only increases demand for precise fabrication processes, but also fast and flexible metrology solutions for asph

For modern production of micro lens systems, such as cementing of doublets or more lenses, precise centering of the lens edge is crucial. Blocking the lens temporarily on a centering arbor ensures that the centers of all optical lens surfaces coincid

Modern optic systems require modern assembly and joining techniques. The trend of keeping production dimensions as small as possible while maintaining or increasing optic imaging capacity leaves little room for mechanical equipment to align the indiv

Due to the large coherence length of laser light, optical path length (OPL) resolution in laser based digital holographic microscopy suffers from parasitic interferences caused by multiple reflections within the experimental setup. Use of partially c

SummaryShiga toxin (Stx)-mediated injury to vascular endothelial cells in the kidneys, brain and other organs underlies the pathogenesis of haemolytic uraemic syndrome (HUS) caused by enterohaemorrhagic Escherichia coli (EHEC). We present a direct an
