Atomic species with two-valence electrons, such as alkaline-earth atoms, offer exciting spectroscopic tools that can bring quantum simulation with ultracold atoms into new directions.

Here we present an experimental setup capable of preparing ultracold bosonic strontium in a two-dimensional optical lattice. By performing fluorescence imaging of a 2D quantum gas with site-resolved resolution, we realize a strontium quantum-gas microscope. In this poster, we discuss the main technical features of our setup, its current status, and possible future directions.
