Magnify small parts

I've just been asked to draw up some very small parts. They are brass plates approx 5mm wide x 12mm long. They have curved ends, cut-outs in the centre and protrusions out from each of the flat sides.



My problem is trying to measure them. What I need is a device that will greatly magnify them, say 10 times, and be able to take dimensions off the enlarged image.



Any clues?
