We have completed the design and testing of a custom high-resolution objective with a long working distance. The microscope consists of a commercial aspheric lens plus a meniscus lens and has a diffraction-limited resolution of 1.2 micron at 766 nm. We have performed some preliminary tests by recording the in-situ density distribution of a strongly attractive ⁴¹K-⁸⁷Rb mixture. The measured size of the cloud is in agreement with the simulated density profiles in this interaction regime. We are going to detect our quantum mixture through its phase diagram with micrometric resolution!
