Optical instruments for earth observation often rely on high performance spectroscopy. One key element in this technology is the dispersing element. Typically used grating designs in Littrow or Offner spectrometers ar...

The facetVISION array camera architecture allows to reduce the z-height of mobile camera modules to 50% of that of a conventional camera module independent of pixel size and resolution while at the same time providing...

For endoscope windows, there are no satisfying solutions for durable AR-coatings on the heavily stressed outer surfaces. We have developed an interference coating which withstands disinfection and sterilization, essen...

A tandem microlens array with arbitrary shaped lenslets projects patterns towards the far-field. Employing intentional channel crosstalk enables dynamic steering of the projected pattern. The micro-optics is mastered ...

Transverse Mode Instabilities (TMI) are a thermally-induced nonlinear effect that results in a fluctuating output beam profile unsuited for most applications. Since their first observation in Yb-doped amplifiers [1], ...
