           | Setting up a tabletop optics experiments is mostly optimizing
           | alignment between different components (lasers, lenses and
           | optical detectors etc), so you get the maximum power or the
           | right kind of superposition. Alignment is linear (get the
           | right distance between two components) or rotational (right
           | angle). So you can build these linear/rotational mounts that
           | will move/rotate your components precisely based on computer
           | commands.
           | 
           | You can probably buy off the shelf robotics components off
           | Alibaba that are better and cheaper at the same time. But I
           | think distributed manufacturing is way cooler.
