How is your laser tracker performing?

Laser trackers are amazing, complex machines. Lots of moving parts. You baby them, of course—they are your most precise measurement device. But you still worry. It’s in your job description.

Now, you’ve got some critical measurements coming up. And it’s been 5 months since your tracker arrived back from the manufacturer’s certification.

Can you be confident in that next reading? Is your tracker performing within Maximum Permissible Errors? How about another 5 months from now?

Living on the Edge… but Never Falling

They get cracked, scratched, and occasionally dropped into the assembly while taking measurements. Brunson Instrument Company offers several options for controlling your SMR so it stays in place or securing it so that even if it does get dropped, it doesn’t get damaged.

Consider these innovative SMR target holders:

The Pharaohs Were a Bit Short-Sighted

The Egyptian pyramids have stood for millennia, but they could have been stronger.

Yes, even after enduring 5,000 years of sandstorms and erosion the Pyramids at Giza still stand tall and proud… but they could have been built even better. Instead of four sides, Egyptian engineers could have used a tetrahedron--a three-sided pyramid on a triangular base.

The stability of a tetrahedron would have made the pyramids even more durable… and maybe even useful. Think of the metrology applications of using that solid structure as a base!

How often do you change the oil in your laser tracker?

A laser tracker provides the ultimate in measurement accuracy. Portable and practical for use in the field, they help many industries ensure quality, safety and efficiency.

However, from time to time, even precise equipment needs verification to ensure that it is still performing within specifications set by the manufacturer (known as MPEs, or Maximum Permissible Errors).

This is exactly why the United States Air Force (AFMetcal) asked NIST to develop an Interim Field Test for laser trackers. That standard became known as IR-8016, the NIST Field Test.

Then why make the same mistake with your Laser Tracker?

Most of us have heard the proverb that ends, "For want of a battle the kingdom was lost. And all for the want of a horseshoe nail." While most companies have moved beyond horseshoes to the high-tech realms of lasers, the failure of the most inconsequential-seeming part of your equipment can destroy your entire measurement operation.
