A laser profiling system can characterize and identify which variables affect product quality and waste. Knowing and creating a process is stable, consistent, predictable, and capable goes a long way toward generating sustainable profit, waste minimization, and end customer satisfaction. Read how to do it here:
Profiling small laser beams and measuring the beam size (or mode field diameter) can be a serious challenge. But it’s critical to measure, especially in such applications as fiber optic coupling efficiency, defect scanning, optical design and optical fabrication process control. Here’s how we suggest you do it
CCD camera beam profilers are very sensitive to light.
So what happens when we consider ambient light? How about other light sources in the area, such as laser pumps?
There are two issues that can be caused by unwanted light getting into the camera:
