Keyence Optical Measuring device

RadconRanger
We have one of these. An IM-6120 I think. I really like the convenience and simplicity of making measurement programs on the device.
My question is this, if anyone can help me:
The manual claims accuracy down to 1 micron in wide field and 1/2 micron in high-def.
Is this, well, accurate?
The intra webs have few resources where I can actually go and see what real-world accuracy is. The company website is not a credible source for anything other than a sales pitch (IMO).
Thanks!

  • We have one that is used quite extensively. I believe that it is quite repeatable and accurate for distances and diameters. But along with that, any imperfections in the piece will cause some variation. I have found that very small radii, usually under 0.010-0.015", it can be a bit unstable. I try not using it for GD&T too much, especially profile. Any spec of dirt or scratch in the lens, could potentially throw this off. True position has limitations as it cannot do MMB on the datum, just MMC on the feature.

    We mainly use it for our flat, stamped parts.
