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.

How to measure a Barcode scanning laser? [Updated]
Measuring the power of scanning lasers such as barcode scanners presents a problem. A bar code laser beam scans back and forth at a very high frequency so an ordinary photodiode power meter will not measure the power in the beam but rather the average power impinging on it, i.e. the power times the fraction of time the beam is on the detector. Therefore, when exposed to a scanned beam, the reading will be much lower than the actual power in the beam. For example, if a scanning laser delivers 2mW to a photodiode sensor and the beam is on the sensor only 1% of the time, the instrument will read only 0.02 mW.
