Design and Characterization of a Custom Aspheric Lens System for Single Atom Imaging

Abstract

We designed an optical imaging system compromising a pair of custom aspheric lenses for the purpose of making a continuous position measurement

of a single rubidium atom in a dipole trap. The lens profiles were determined

with optimization and ray-tracing programs written in Fortran. The lenses were produced by Optimax Systems and found to perform as predicted, imaging a point source to a minimal spot size along a wide range of emitter positions.
