Reflect the beams to illuminate the targets.
Illuminate the targets with the right colors.
Mirrors are the most basic components, they reflect beams. You probably already guessed that...
Some mirrors reflect on a narrow angle, others on a larger one.
Semi-Mirrors are like Mirrors, but they reflect only from one side. From the other side, they are transparent. Like in those Cop-Movies. They can be used to combine beams.
Like the regular Mirrors, Semi-Mirrors come in two flavours as well.
Filters are only transparent to certain colors. All the other colors get filtered.
The splitter can be used to split a stronger beam into two less strong ones. What might be less obvious is that it can also be used in reverse to combine two beams into a stronger one.
The prism splits a laser into all the colors of the rainbow. Or in our case, all three base colors. It can also be used to combine colors, but only when they come from the right direction.
