Recalibrating Your Laser Power Meter for Long-Term Accuracy and Reliability
We’d all like to imagine that our things will stay in mint condition forever. But we know that’s not the case. Just like laser degrade (and therefore must be measured), the measurement equipment itself will slowly drift away from its precise calibration.
This is why we recommend yearly calibration. If you aren’t sure when your laser power or energy is due for recalibration, you can check by connecting it to a meter. If it needs to be recalibrated, a notification will pop up on the first screen.
Here’s how the recalibration process works.

Integrating Spheres for Lighting and Laser Diode Measurement
An integrating sphere is a powerful tool to capture all the light of a widely divergent beam. The sphere scatters light uniformly over its whole interior.

Ethernet Laser Power Meter
You can now measure your laser directly from the Ethernet network, without any need to go through to a PC.
Ophir’s new EA-1 is an Ethernet Adapter which can be used with virtually all power sensors to turn them into an Ethernet laser power meter.

Laser Monitoring in Your Factory Line – with Profinet
“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?”
Uh-oh.
