2 End view of the GP-B telescope after it had mounted onto the rest of the Science Instrument Assembly. The small black box contains the highly specialized photo detector that will keep track of the guide star.
3 Looking down at the top of the telescope's beam splitter array. The two protusions behind the mirror plate contain the Diode Mount Assemblies.
4 Side view of the beam splitter at the top of the telescope.
5 Backlit view of a prototype telescope optics.
6 Ken Bower with the telescope
7 Professional photograph of an early telescope model.
9 Early assemby of the SIA ( Science Instrument Assembly). The telescope (front) is shown bonded to the integrated quartz block. The gyroscope lines (visible in the back) protrude from the quartz block.
10 Looking down through the outer window of the probe into the telescope.
11 End view of a partially integrated telescope assembly.
12 Telescope detector chip placed over a postage stamp for scale.
13 Micrograph of the telescope detector array.
14 The detector package assembly is mounted to a fixture for vacuum testing.
16 The telescope Diode Mount Assembly (DMA) poses next to a dime.
