  10. Signal-To-Noise Ratio vs Calibration Uncertainty vs Repeatability In Laser Power And Energy Measurement 7/6/2020

    It is common to search for the measurement solution with the lowest uncertainty of measurement for laser processes involved in demanding applications such as medical device manufacturing or aerospace parts manufacturing, where traceability is key to a production line. Calibration uncertainty of a laser power meter or energy meter may not be the only specification needed checked. Repeatability, linearity and noise equivalent power or energy are other specifications that must be checked out as well. Let’s make it simple! This article will help you select the right detector for your laser measurement needs and quickly.
