We present Zerodur®-based optical components for applications in a transportable aluminium ion quantum logic optical clock.

A transportable optical ion clock requires a compact and robust setup. These requirements are fulfilled by rigid Zerodur®-based breadboards[1] as shown for sounding rocket missions. We present a distribution board, where light with the wavelengths 375 nm, 397 nm, 422 nm 854 nm and 866 nm is coupled into an LMA fibre. The temperature and acceleration stability of the setup will be characterized and compared to a classical optical setup. As a second step, we show a design study of a Zerodur®-based double pass AOM setup for a wavelength of 397 nm. Both setups are developed for a transportable aluminium ion quantum logic optical clock. However, such Zerodur® breadboards could become part of robust laser systems for a broad range of quantum optics experiments in the future.
