Thanks for the code! But I didn't mean the coil symbol. Actually I'm
looking for a symbol as in Fig.3 in:

http://zone.ni.com/devzone/conceptd.nsf/webmain/C83E9B93DE714DB08625686600704DB1/$File/AN078.pdf

--> more a zigzag line instead of a coil.

Thanks for the link! Together with the code you posted I should be
able to create the symbol I was looking for.

Sorry for not beeing precise enough. I would like to draw a linear
polarized beam [A] which passes through an objective with a lambda/4
filter. This beam then becomes circular polarized (i.g. clockwise) [B]
and gets reflected from the object of interest. This reflected ray is
now polarized counterclockwise [C]. After it passes the lambda/4 plate
again the beam is turned by 90 degrees [D] and can pass an analyser.

I'm looking for a way to have these different rays [A-D] displayed
differently. So far I have seen different methods:

- F.ex. dashed and solid lines for [A and B], double lines/double
  dashed lines [C and B];

- Solid lines with an arrow crossing the line [A]. The direction of
  the arrow changes is the polarization changes [B].

- Using different colors (I'd like to stick to black and white
  though).

Are there any rules that apply to this kind of display?

Or should I just go with something that suits me best?

TIA,

Patrick
