Towards high-resolution imaging of RbSr molecules in an optical lattice — •Simon Lepleux, Noah Wach, Premjith Thekkeppatt, Digvijay Digvijay, Junyu He, Klaasjan van Druten, and Florian Schreck — Van der Waals-Zeeman Institute, University of Amsterdam
Polar, open-shell molecules in their rovibrational ground state exhibit a rich structure along with long range electric dipole interactions and a magnetic dipole moment. Polar molecules in an optical lattice impart long range interactions between lattice sites, which gives rise to exotic phases and extended Hubbard models. Utilizing a high-resolution microscope with single molecule addressing and manipulation techniques in an optical lattice will enable us to study spin lattice models.
We present the design and characterization of a custom microscope objective for an alkali - alkaline earth optical lattice experimental setup that offers us single-site resolution. Our infinity corrected microscope objective is constructed with commercially available lenses. It has a numerical aperture of 0.4 and a long working distance of 42.6 mm. The performance of the microscope is diffraction limited from 461 nm to 795 nm.
