The guider camera has an integrated housing which is made from CNC-milled pieces of aluminium. The various pieces are dip-brazed together and then anodized.
The header assembly fits into the front cavity, and is sealed in place by a faceplate with a 1" x 1" square quartz anti-reflection coated window.

Inside the housing, there is a water-cooled heatsink (for the TEC) between the front and back cavities. There are two pipes which transport the coolant from the heatsink to the back of the housing.
A backplane board fits into the back cavity and is screwed onto the heatsink. It has pins which reach through holes in the heatsink to connect to the header board.
The four main circuit boards fit into slots in the walls of the electronics box, and slide into the backplane.
A mechanical drawing of the housing is here (.stp format). The camera mass is approx 950 g.
