Do you want 10 beams all going in the same direction?
If not you could buy a diffraction gratting which are pretty damn cheap

As far as I know, having one laser turning into 10 parallel beams that have good divergence and diameter, is impossible. I am not sure how it would be done, the easiest thing to do would be to get a diffraction grating that will make a "cone" of beams.

Why not use ten 5mW modules? $40. Any red beam split that many times or sent through that many optics will only be 5mW per beam anyway.

I agree with cyparagon. BUT if you really want to do it using one, you could get some partially silvered mirrors so that a certain amount passes, and a certain amount gets reflected into the next pertially silvered mirror etc. But that would really be a pain in the ass and you will lose quite a bit of your 10mW to the optics. With 10 separate modules you will have much more power in your beams and it will be a lot easier and cheaper.

how about a diffraction grating which makes ten lines and then put a mirrors on each line

^I thought about that, too. But most of the beams would have differing intensities.
Whoa, he's only got 10mW to begin with?? I was imagining a 300mW DIY or something of that nature. I missed that part... Yeah, this is optically unfeasible.

I built the Predator's sight http://www.laserpointerforums.com/forums/YaBB.pl?num=1211822319/0#0 just add 7 more!

Just out of curiosity , what do you want this for? :-/A laser field?

Getting a good (meaning REALLY REALLY narrow slits) diffraction grating would give you about the same intensity for each beam.
If you want a matrix of beams, get two diffraction gratings and put them 90 degrees to each other and shine the laser through. For a line of beams, use 1 diffraction grating.
Since they emerge as a cone of beams, get a converging lens to make them parallel. It'd be difficult work positioning the lens to make them parallel though.

you cant make them parallel with a lens, you'll also make each beam convergent to a focal point and divergent beyond that.

Nope, something like this would happen, since the individual beams are not made of a single line of photons. :
Just try it with a real laser beam and lens and you'll see what I'm talking about.
Just look at the center beam of your diagram.It looks like if you point a beam at the center of the lens it will maintain the same divergence and diameter like it passed through a flat piece of glass.Does that happen that way in reality? No. : That's because the lines in the simulator reprezent single photon trajectories, and what they would look like through a lens.
