MKS Ophir, Light & Measurement
Laser power or energy output directly affects a system’s ability to perform reliable and correctly. Consequently, accurately measuring a laser’s output is fundamental to ensuring that it performs reliably and correctly — from when the laser is first manufactured to its integration into a system, and to its final application.

Slutzki discusses when and why absolute calibration accuracy matters (and when it doesn’t). He shares best practices for maximizing the accuracy of readings, and he provides an overview of how to understand a power meter’s accuracy specifications and where the numbers come from.
