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:

A Better Mousetrap

The Great Depression may have been the best thing that ever happened to Brunson Instrument Company.

The founder's story is like many of the early 1900s: an ambitious, gifted and intelligent young man moves from a hardscrabble farm (and a log cabin!) to the big city to look for work.

Amber Nelson Brunson was forced to leave school after the 3rd grade to help his family make ends meet, but what he lacks in formal education he makes up for in mechanical aptitude, design skills and determination.

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!

Six Challenges of Laser Trackers

Deighton Brunson
By Deighton Brunson on Mar 7, 2019 4:19:23 PM

Picture what might have happened if you gave R2-D2 a laser interferometer. He may have become the first laser tracker in that galaxy somewhere, long ago and far away. There are some similarities, after all, between R2-D2 and trackers. They are both sophisticated devices that beep, spin their heads, and project light. However, instead of projecting images of Princess Leia, a laser tracker uses encoders and a distance-measuring technology to track and specify the location of an SMR target in 3-D space. Both are pretty cool.

And just as Luke had to understand R2-D2, laser tracker operators need to fully understand their trackers to get the most out of them, and avoid introducing errors, while measuring. Below is a list of some of the issues that you may want to watch out for when using a laser tracker.
