Paper Abstract

A full size Double Corner Cube (DCC) assembly was delivered recently to NASA's Space Interferometer Mission (SIM) PlanetQuest testbed at JPL. The DCC was developed at CSIRO's Australian Centre for Precision Optics (ACPO) to demonstrate the fabrication of the flight size DCC fiducials. The DCC was assembled from three 30°, high precision ULE glass wedges and a 132 mm diameter base plate. After alignment to sub arc-second angular tolerances, the three wedges were chemically bonded to the base-plate. Comprehensive testing was performed on the assembly to certify the compliance of several parameters including the dihedral angle errors, figure of all reflecting surfaces and the Non Common Vertex Error (NCVE) of the DCC. This paper elaborates on some of the metrology and the certification results of the delivered DCC assembly as well as the chemical bond strength tests.
