Changes in your sphere? Have No Fear!

Integrating spheres are very useful for collecting light to be measured. However it is very important to understand how integrating spheres work in order to be assured that measurements made are meaningful.

HOW TO MEASURE UNSTABLE LASER POWER

We’ve all been there before.

You just want to measure the laser power with a simple power meter, but before you write down the reading, you notice it’s changed.  You take a closer look and see that it’s changing continuously.

StarLab 3.30 Pass/Fail limits feature – A closer look

User-defined pass/fail limits allow setting the upper and lower bounds of an acceptable measurement, and getting a clear indication when the measurement deviates from these bounds.

In case you weren’t aware -The ‘pass/fail’ feature can be used as a tool to perform QA final inspection on the laser. Developers can use this to demonstrate the results of a prototype laser to Management (or even VC’s!) as part of the pitch for funding.

How?

Technical Tip: How to select a power and energy meter – part 2

So, as we’ve started discussing the best way to pick a power meter last week, we’ve reached the third piece of data we need – and that is the laser wavelength. Why is it so important? In order to match it to the sensor absorber characteristics.

We need to select a sensor whose wavelength is within the measurement range of the sensor, power rating is equal to or higher than the maximum power we will measure, whose aperture is larger than the laser beam diameter so that it will contain the whole beam, and whose damage threshold is higher than the maximum expected laser power density at the given wavelength. The sensor absorber should be selected so it matches the wavelength for higher absorption.
