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.

Ophir Celebrates 40 Years!
From its humble beginnings in 1976, Ophir has grown to become the world leader in laser power meters and other laser measurement technology.
I spoke to Ephraim Greenfield, Ophir founder and CTO to get some insights on the origins and progression that Ophir took through the last four decades.
Here’s what he said.
