Micro Tubing Concentricity Checking using Crosshairs

J

I have heard that crosshairs are used when measuring concentricity in micro tubing. I wonder: how does concentricity get measured with the aid of a crosshair?

I'm also looking for tubing at sizes that are less than 0.1 inch to validate a system I developed to find concentricity in less than 2 minutes without having to cut the tube at exactly 90 degrees. Again, this is for micro tubing typical to the medical device world where a gauge system cannot be used to find concentricity. You are welcomed to contact me: jerry(at)imagingandanalysis(dot)com.
