High Resolution Imaging

# Goal

We would like to be able resolve individual atoms in a 760nm square lattice.

# Approach

The diffraction limit tells us that we cannot have two point sources closer than $\frac{\lambda}{2NA}$ and hope to resolve them. Therefore, in order to get the best resolution possible, we are trying to make $\lambda$ as small as possible by collecting photons from the 405nm transition in 40K, and making the numerical aperture, $NA$, as large as possible by getting very close to the atoms:
