The Executive Summary
Start of assembly and "First Light"
55 days and 78 days respectively after defining the requirements.
The blue panels are foam insulation.
The Details
Left: Base; Middle: Base with shock
mounts;
Right: Base with frame to house Integrating sphere;
Left: Bottom plate and Invar metering
truss added;
Right: Thermal enclosure support frame added.
Left: First 1/4 inch aluminum plates
for thermal control;
Right: Fully assembled instrument. The "gold" baffle
sits on top of the star plate and extends to just below the camera
optics. The top cylinder is the Cryotiger cooler and the next
to top cylinder is the dewar housing the CCD. The interior aluminum
walls are temperature regulated with thermal-electric-coolers/heaters.
The blue Labsphere can be seen in the bottom.
