KinAiry is the comprehensive, independent solution for laser tracker evaluation, utilizing NIST's new Interim Field Test Procedure IR-80161. The KinAiry system provides a set of traceable measurements designed to verify volumetric performance in your environment. The result is a colorized graphical analysis that quickly shows the overall health of your tracker…regardless of make or model.
Everyone knows that almost all materials will expand when the temperature rises, and shrink when the temperature falls. Often this is not a problem, but in the measurement world, this effect can cause mischief. Nobody likes to measure things with a ruler that is capable of expanding and contracting. It's the same as the old story about the man with two watches – he never knows what time it really is. So wouldn't it be great to have a measuring device that was the same length regardless of the temperature?
It sure would! We come close to that scenario by using "Invar". Invar is a very special alloy of iron and nickel, with a few other things thrown in, such as silicon and manganese. The benefit of Invar is that it has a very low coefficient of thermal expansion. This of course means that it changes very little when the temperature rises or falls. In fact, the alloy gets its name from the fact that it has a relatively invariant volume under varying temperatures.
For over 90 years, Brunson Instrument Company has designed, manufactured, and installed thousands of products for the 3-D metrology and alignment markets – and trained the people who use those products. On the simple side, we’ve manufactured precision parts and created subassemblies for metrology companies who integrate those products into their own. On the complex side, we’ve manufactured entire systems that we’ve designed to meet our customers’ specs, providing needed solutions for measurement challenges.
