Improved methods and systems for routing and aligning beams and optical elements in an optical device include a multiplexing device andor a demultiplexing device, which includes an optical alignment element. The ultrasonic horn is connectable to a transducer, and a crystallization tube is adjacent to the ultrasonic horn. The novel segmented apparatus and installation method further provide for a centering collar 113, an anchor positioning means at level force pivoting plates 194, and pivoting plates 194 positioned 40-50 degrees from vertical.
