Watch: How to Measure Low Power, Slowly Pulsing Beams (“Low Frequency Power”)
Are you trying to measure a low-power, slowly pulsing beam (think of a VCSEL beam for example) – and getting frustrated? Measuring low-power, slowly pulsing beams using photodiode sensors can be surprisingly tricky. Learn about the technical challenges you’ll face when trying to measure such beams, and about the Ophir solutions that will help you.…

Measuring Very Low Power IR Lasers with the RM9 Radiometer System
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;…

Special Photodiodes for Special Lasers (and Other Sources)
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…

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.
