Abstract
We present a compact and robust setup to optically transport ultracold atoms over long distances. Using a focus-tunable Moir\'e lens that has recently appeared on the market, we demonstrate transport of up to a distance of 465 mm. A transfer efficiency of 70% is achieved with negligible temperature change at 11 K. With its high thermal stability and low astigmatism, the Moir\'e lens is superior to fluid-based varifocal lenses. It is much more compact and stable than a lens mounted on a linear translation stage, allowing for simplified experimental setups.
