How to Profile Large, Small, and High Power Laser Beams
Don’t you wish there was a one size fits all beam profiler? I know I do. Problem is that the very thing that makes a beam profiler so perfect for one laser renders it useless for a different laser. At risk of overcomplicating matters, we like to provide our customers with maximum flexibility. So you…

Two Different Ways to Expand Your Laser BeamAre You Using the Right Method?
Whether your laser beam is too small or too large, you need to add some optics (an expander or reducer). But there are two fundamentally different types: reimaging and Galilean telescope optics. Which one is right? Depends on your application. But before I explain when to use each type, let’s take a look inside these…

Laser Measurement PC Interfaces
If all your laser measurement work involves a laptop or a PC, rather than a stand-alone meter, one of Ophir’s direct-to-PC interfaces could be an ideal solution. These are full-fledged Laser Power and Energy meters, but instead of having a separate on-board display, the PC becomes your display. In this video you will learn about…

Measuring the Power of a Pulsed Laser Beam
Pulsed lasers are complicated. When you’re dealing with a CW (continuous wave) laser, things are nice and simple. The laser light has a certain power, and that’s exactly what you’re measuring with your laser power meter. But a pulsed laser is much more complex. Besides power, you also need to worry about pulse energy,…

How to Use the StarLite with Your PC. And Why
When we released our newest laser power meter – the StarLite – last year, we wanted it to be as simple as it could be. Yes, that means there would be fewer features, but that was the point. A simple meter at an affordable price. The main goals were:

Do You Know the Power Density of Your Laser?
Lasers can be dangerous. For you, for your workspace, and for your measurement equipment. Some people assume high power is the problem and low power is safe. This isn’t necessarily the case, though. What you really want to look at is the power (or energy) density of the laser.
