There are two main technologies commonly used today for measuring laser beam powers: Photodiode-based sensors, used for measuring low powers (from pW up to several hundred mW, typically); these are limited to spectral regions from the UV to the near IR, depending on the specific semiconductor used, and Thermal sensors, used for measuring higher powers;…

For most cases of laser (or LED) power measurement, selection of a proper sensor is fairly simple – it all depends on power level and wavelength. But for some cases, the application demands a more tailor-made sensor. Ophir’s line of “Special Photodiode” sensors are made for just that purpose. There are now Special PD sensors…

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.
There are several considerations when you’re trying to maximize laser power meter accuracy. One that I don’t usually mention is perhaps the most obvious question: How do you know the entire laser beam is actually hitting your sensor? I mean, if you have a visible laser, fine. But most lasers these days are in the…
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.
