Vacuum chamber for optical spectroscopy

I started designing an vacuum chamber for our spectroscopy setup at work to measure fluorescence at low pressure. I would like to share with you some early plans of it. This is an image that I made using Autodesk Inventor to show how it may look finished.

The body will be made of aluminum, the windows (far on the left) probably quarz. The NW25 flange on top is for connecting a vacuum valve and pump.

I hope my boss will like it :).
