Titel
High-precision assembly of micro-prisms
Abstract
An assembly of four prisms in a so-called butterfly arrangement had to be produced by adhesive joining. The parallelism of the four output beams was required to be below one arc minute. Using active alignment and a specially designed algorithm a beam parallelism of less the 2 arc minute was achieved for the worst case while the mean deviation amounted to less than 0.4 arc minutes.
