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.

“Power from Pulse” – How to Measure High Power Lasers with Small Sensors
A few months ago, I mentioned a new method for measuring kilowatt lasers without water (or even fan) cooling.
The idea was like this: Even a small 50 W sensor can handle high powers for a short amount of time, like a few seconds. Several of our sensors’ specifications were adjusted to reflect this.
For example, the L40(150)A is meant to measure 40 W continuously, but it can actually measure 4000 W for a second.

How to Trap More Than 99.9% of a Laser Beam
Sometimes a laser is used in a “pass-through” setup, which begs the question: What happens to the laser after it passes through?
Consider for example a sensitive camera that is used to profile a laser. Beam splitters are often used to deflect only a small percent of the laser intensity into the camera. The other 90% or more passes straight through the splitter.

Can You Measure Laser Power with the Sensor on an Angle?
Glad you asked.
Like many answers to many questions, the answer here is “sometimes yes, sometimes no.”
To explain this, we must look at each of the three main types of laser power/energy sensors:

StarBright: Advanced, Yet Easy-to-Use Laser Power Meter
In order to measure your laser, you need two things:
Thing One: A sensor, to convert photonic power into an electrical signal.
Thing Two: A meter, to measure the electrical signal, digitize it, and display the results.

Measure Laser Power on Your Android Phone
Some people prefer to use a PC to display their laser measurements. Some use a power meter.
But if you are a service technician and find yourself lugging equipment from one site to the next, this might be your saving grace.
Ophir recently released an Android app called StarViewer.
