Abstract

The last step in designing and building instruments are the verification and acceptance tests of the assembled units and of the final instrument. For instruments, which are engineered to work at the limit of feasibility, these tests must be accurate and stable at a level much better than the expected performance of the instrument. Particularly for interferometric instruments, this requires special care for the test planning and implementation in order to achieve the necessary performance. This paper describes the verification and acceptance tests of the PRIMA DDL optics in terms of wavefront error and tilt requirements as well as the assembling and aligning accuracy. We demonstrate the conformity of the optics and point out the limitations of the test methods.
