Figure 2: Prototype CO#1.

The mechanics team is working on several prototypes already. In the following figure is shown prototype CO#1.

* Several tests have been finished.
o Temperatures
o Measurements
o Maladjustements
o Precise measurements
* Tests at low temperature including lenses are on the way

Structural and thermal design

The structural and ternal design has these key characteristics:

* Vacuum camera, security factor 7
* Thermal design on the way
