It has a single can with the CD, DVD, and blu-ray laser diodes inside.  The outgoing and return beams are separated by a pair of polarizing beam-splitter cubes.  The only moving parts are a lens on a micro stepper motor controlled linear stage, and the objective lens.
It has 1 lens with 2 lasers, one for CD/DVD and one for BluRay discs.
