Buyer's checklist for laser power and energy meters

There are lots of things to consider when looking for a laser power meter or energy meter. Business needs and laser specifications can vary from one organisation to another and from one application to another. This led Gentec-EO to create more than 700 measurement instruments.

It is all too easy to purchase an instrument that is less than optimal for your specific needs or feel overwhelmed in the process. From measurement accuracy to cooling requirements, damage thresholds to portability, every detail matters when selecting the best instrument for your application. That's why Gentec-EO has put together this checklist of all the things you should think about before you decide which instrument to buy. For each item, there is a brief explanation about what you should look for, with direction to more in-depth resources when relevant.
