Design and Implementation of a Versatile Imaging Objective for Imaging of Ultracold Mixtures of Sodium and Lithium
Abstract
This thesis presents the design and implementation of a high resolution objective lens for imaging ultracold atomic clouds of sodium and lithium in the NaLi experiment. The lens has been developed using the ray tracing software OSLO. The design process aimed for an objective lens that performs diffraction limited at a high numerical aperture of 0.41 for both imaging wavelengths of sodium (589nm) and lithium (671nm). Additionally, the lens design accounts for the requirements regarding the installation into the existing experiment, determining the diameter and working distance of the imaging objective.
