A high-resolution imaging system for quantum simulation experiments — •Micha Bunjes, Tobias Hammel, Maximilian Kaiser, Philipp Preiss, Selim Jochim, and Matthias Weidemüller — Physikalisches Institut, Universität Heidelberg, Im Neuenheimer Feld 226, 69120 Heidelberg (Germany)

Detecting ultracold Lithium-6 atoms in a new setup for quantum simulations requires a high-resolution imaging setup to resolve and manipulate single atoms, and to image versatile optical dipole traps.

For this we design a system including a high NA objective, featuring diffraction limited broadband performance, a large field of view, and an external back focal plane to retroreflect a collimated MOT beam. Characterizing this system in detail allows us to improve its performance even further and counteract aberrations.

Further we are developing a mounting structure, enabling a passive alignment relative to the imaging objective while maintaining good optical access. Additionally, the mounting around the vacuum viewports is designed to support a modular approach for any optics near the atoms, improving the flexibility of the experiment.
