Standard optical component symbols?

[wotanub]

Of course we all know the standard symbols to use when drawing electrical circuits, but is there an analog for optical setups? I'm working of a poster and most of the symbols I'm using are just boxes with labels next to them, or just lines for mirrors and lenses.

I don't believe so. Optical systems are usually nowhere near the complexity of an electronic circuit.
