SOPHIE spectrograph
with cover installed

The cover assembly was installed at the end of December 2006. It is made from insulated foam and shields the spectrograph from thermal turbulence within the chamber, reduces stray light and protects the mirrors from dust. It is now expected that the thermal stability of the spectrograph will be better than 0.01°.

Two sides of the cover (right side and back) can be opened for access to SOPHIE. The cables running on the ceiling, on the floor and hanging on the extreme right gather data from various temperature sensors installed outside and inside the cover.
