In prepartion for installing the black out curtain and moving the Al bar, I removed all the optics form the table (Fig.1). They are now stroed in the big desiccator (fig .2).

I also tried rearranging the Thorlabs lens case but gave up since it was all mixed up.

During this work, I notice most of the the pedastals and mirror mounts I stored inside the box labelled cryogenic cavity had disapperead (fig.3).
