“You can do Profinet, right?”

John had just ordered 10 laser welding stations for his new car manufacturing facility. As a laser system integrator, you talked to him in detail about all the specs. What exactly does he need from the laser? What sort of control equipment does he have? What else does he need?

John added, almost as an afterthought – “The facility is in Germany, so of course we want all the lasers and devices running on Profinet. You can do that, right?”



Not everyone knows this, but almost all Ophir power and energy sensors can be used with four standard fiber adapters:

Of course, any fiber can be measured by an Ophir sensor by taking a free-space measurement – placing the fiber tip a few mm or cm from the sensor and letting the laser beam continue to the sensor.

However, in many cases it is convenient to use a fiber adapter to connect to a measuring device.

If that’s the case, here’s what you’ll want to do.


Modern production facilities must constantly increase throughput, at less cost, with less scrap, and with minimum downtime. In this video overview, you will learn how application of new, advanced technology in measurement devices, can help both designers and users of industrial laser systems to optimize and control their processes, so they can accomplish these goals and achieve consistently good results – both in quality and quantity.

Focus shift monitoring of high power lasers


Measuring the focal spot of a high power laser is challenging, at best.

The main issue is that when a high power laser is focused down to a small point, the power density can be extremely high, typically high enough to damage any sort of measurement equipment you would use.

The solution?
