Wouldn’t It Be Nice to Automate Your Laser Beam Analysis?

What is automation? The dictionary defines automation as: “the technique of making an apparatus, a process, or a system operate automatically.” We define automation as: “the creation and application of technology to monitor and control your laser system.”  In other words, automation at Ophir means using or creating outside applications to measure your laser. Contact…

How to Measure M-Squared – Two Choices

“When you come to a fork in the road – take it.” Unfortunately, Yogi Berra’s sage advice has not worked well for most people. There’s an age-old decision when it comes to getting a job done: difficult, but quick or slow and steady.  As Phil Keoghan likes to say about “speed bump” challenges in The…

A Quick Guide to Optical Measurement Devices

All I know is I want to measure light.  Should I use a light meter, lux meter, laser power meter, optical power meter, radiometer, photometer, spectrometer, or something else I have yet to hear of? Good question. I actually set out to write a blog post about optical power meters, but as I sifted through…

How can you be sure that your laser’s output is pure laser light?

We’d all love to imagine a world where lasers always perform exactly as they’re meant to.  Unfortunately, the all-too-often reality is that lasers can malfunction, just like anything else.  The question then becomes: “How can I figure out what’s wrong with my laser?” Contact us
