I just looked at the Aculux laser site. It is a good idea, but the accuracy is only 0.003". I know the touch probe system is time consuming and a bit of a pain since what you actually get is an offset of the surface, but the accuracy is down to 0.0002" (at least that's what they advertise). I have worked with other conventional CMM's, an this was standard practise. The trick was to have software capable of generating the true offset surface without taking two days to process.
Hey Greig, do you guys have a website?
