|These are three of the backing plates made of Aluminum Nitride that will hold the CCD chips in the mosaic at the focal plane. The Invar plate that they are mounted on is 5" diameter.|
|The Aluminum Nitride and Invar assembly is put into liquid Nitrogen to check the thermal stability of the components at typical operating temperatures.|
|This is a key component of the CCD mounting fixture. The Aluminum pieces are held by rods made of G-10 (a form of glass epoxy). These rods will deflect sideways, but minimize movement in the compression/expansion direction.|
Following are various views of the CCD mounting fixture
that uses these Al/G-10 components. The central cylinder is
isolated and suspended by these units which will constrain motion to
the focus direction only.
