The All-in-One Laser Beam Analysis Machine

So, you want to measure your laser… What comes to mind first? A laser power meter?  Okay… Let’s say I’m using a laser to cut sheets of metal and I have a power meter to check that it is outputting the correct power.  But even if I know that my laser produces 50W with 99.9%…

Bottom Line: What Is Beam Profiling Dynamic Range?

What does dynamic range really mean in a laser beam profiler?  I don’t mean the technical definition.  What are its implications?  How will having a specific dynamic range help you understand what the camera or scanning slit profiler can do? Contact us

Avoid Thermal Lensing When Profiling Your Laser Beam!

So, your laser power is a little high.  No problem, just stick some attenuating filters in to lower the power, right?  Not so fast. In some cases this can cause thermal lensing.  If you’re not familiar with it, thermal lensing basically means the heat of a laser beam can distort the filter medium and create…

Don’t Let Lasers Ruin Your Solar Cells!

Picture this: After decades of providing the best quality solar panels, you find competitors edging you out of the market with a better profit margin. They’re using the new laser scribing process to produce solar cells more efficiently. At first, you want to stick with the tried and true methods, but at a certain point…

How to Analyze High Power Laser Beams

Every day a new application if found for lasers. High power lasers are especially useful for material processing, but are also used prevalently in scientific research and military applications. It is often crucial to be able to “see” the profile of a laser beam. If one is using a laser to cut metal, for instance,…

Measuring widely diverging beams

We often are asked about measuring the power of widely diverging beams and how to do so. First of all, Ophir has integrating sphere power meters designed for divergent beams of up to +/-40 degrees divergence. These are the 3A-IS and 3A-IS-IRG power meters. These power meters are primarily for low power beams of under…
