A Glimpse into the Life of Ophir CTO Ephraim Greenfield
What’s the one quality you need to be a great scientist? Intelligence? Diligence? If you ask Ephraim Greenfield, co-founder of Ophir, he’ll probably tell you it’s a mixture of luck and being willing to just go ahead and try something. Contact uscontinue reading
There’s No Wrong Way to Use a BeamTrack Sensor
Unlike a traditional thermal sensor which is basically just used for power, the BeamTrack sensor can measure several different aspects of your laser. We also call them power/position/size sensors, since those are the three fundamental functions of a BeamTrack sensor. But it doesn’t have to stop there. Yes, if you need to measure your beam…continue reading
Industrial Laser Beam Measurement with ModeCheck
Spiricon’s ModeCheck enables quality cutting, marking, drilling, and ablating. Instantaneously “see” your beam and reduce set-up time between jobs. ModeCheck provides real-time “mode burns” – eliminate hazardous acrylic vapors. Optimize your laser’s efficiency: reduce cost per part, predict laser preventative maintenance, increase manufacturing efficiency. Contact uscontinue reading
How to Measure LED Power – Accurately
LEDs are replacing more and more traditional light sources as efficient, durable, cost-effective alternatives. But should we measure them the same way? In a way, this is a lot like the introduction of automobiles, replacing the traditional alternative: horse-drawn carriages. When people switched to driving cars, they quickly realized that it makes no sense to…continue reading
How to Find the Perfect Laser Beam Profiler
I wish I could tell you that there is one super-profiler, and it will profile any laser with 100% accuracy! Of course that’s a pipe dream. There are tons of different laser types, so it stands to reason that we’ll need several different profilers to cover the range of lasers. There are cameras and scanning slit…continue reading
How to Measure Stacked Laser Diode Power
Picture this. Your boss has been bugging you about the low welding yields lately, and you can’t disagree. As the laser technician, you have to find out why the laser welders haven’t been working as well as they should. It’s not just that they are slower than advertised, but they’re producing imperfect welds. You know…continue reading
How to Measure Very Low Power Infrared Lasers
There are many different types of lasers.  UV, visible, infrared, Terahertz. Nanowatts, milliwatts, kilowatts. Lasers for industry, laser for medicine, lasers for telecommunication. Contact uscontinue reading
Measuring Power of Scanned Laser Beams
- by Mark Slutzki
In this video, you will learn how the BC20 sensor enables correct power measurement of scanned beams, as are used in barcode readers, laser shows and similarly challenging applications. Contact uscontinue reading
BeamGage Professional and BeamGage Enterprise allow programmers to access all the functionality of the graphical user interface through LabView, Visual Basic, C++ and C#. This video is a short introduction to automation with a LabView demonstration. Contact uscontinue reading
Can a Small Integrating Sphere Measure Your UV LEDs?
Does this conversation sound familiar to you? “Hey boss, how many LEDs should I use?” “Uh, why don’t you add a few more, just in case.” “How many more?” Contact uscontinue reading
Your Map to Laser Beam Profiling Accessories:Which Cameras Do They Work With?
Few lasers can be profiled directly with a camera. Attenuation is almost always a must. Sometimes you might need additional optics as well. I discussed how to determine what accessories you need and how to use them in a couple of other posts: ND filters Expanding optics Reducing optics But there’s another consideration I haven’t…continue reading
What’s Harder to Measure:A Short Pulsed Laser or a CW Laser?
On the one hand, CW lasers will almost always have a higher average power. That means it’s harder for the power sensor head to cool down. This is not an issue with most short pulsed lasers. However, Contact uscontinue reading
