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.
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…
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…
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…
Measuring the emitted power of an LED can be tricky; it is different in some important ways from measuring the power of a laser beam. This video shows you how to use the Ophir 3A-IS Integrating Sphere Sensor, along with the Auxiliary LED accessory, to easily make accurate measurements in LED applications.
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…
There are many different types of lasers. [citation needed] UV, visible, infrared, Terahertz. Nanowatts, milliwatts, kilowatts. Lasers for industry, laser for medicine, lasers for telecommunication.
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.
There’s a common misconception when it comes to choosing an energy sensor to measure high frequency pulsed lasers. The confusion begins when we look at the energy sensor specs and compares them to our laser.
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.
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?”
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…
