History of Metrology: 5 More Ancient Measurement Tools

In previous posts on this blog, we’ve discussed Tools of Metrology that either can be found in your daily life or were ancient measurement tools, and it’s a topic we’d like to return to here. While we often track the refinement in measurement units and tools since...
The Origin of Lasers

The Origin of Lasers

Did you know that discovery of Laser properties was a byproduct of microwave “Maser” research done at Columbia University in 1951 by Charles Towns? In 1953, Charles Townes debuted a device he’d been researching at Columbia University that would stimulate ammonia...
What is Machine Tool Calibration (MTC)

What is Machine Tool Calibration (MTC)

In our “What is Calibration?” article, we discussed how calibration is a two-step process of first evaluating equipment performance against a reference standard and second using that information to improve equipment performance. And we looked at how many of the...

3 Sources of SMR Inaccuracy

As we discussed previously on this blog, Spherically Mounted Retroreflectors (SMRs) are made up of three key components: the sphere, the corner-cube reflector, and the reflective coating on the reflector. Each of these components must be manufactured and assembled to...
What is Calibration?

What is Calibration?

Laser Trackers naturally see an erosion in their performance over time. Wear and tear from regular use, plus a host of environmental factors, can create slippage in accuracy. Fortunately, there are many ways to test your Laser Tracker to determine whether it is fit...

[New Video] What is Metrology?

What do you think of when you hear the word Metrology? If you pictured industrial environments with lasers being used to measure precise dimensions, you wouldn’t be wrong. But the scope of Metrology is actually much wider than the narrow, manufacturing-based...
