[pstricks] transmission grating in pst-optexp (Christoph Bersch)

[Steffen Wittek]

Hi Christoph,

thanks for your help. I only need the transmitted beams. Ideally there 
are no reflections. The transmission gratings work like the normal 
gratings only that they are transmissive. The operation is shown here:

Do you think that the variant can be extended. Or is there a new object 
needed alltogether?

Steffen
