Tech tip: Measuring Power Out of a Fiber

There are many applications that involve measuring power out of a fiber, where the power is in the range of tens of µW to a few mW. A customer recently found that every time he disconnected the Fiber Optics connector from the adapter and then reconnected, the power read 50-100 µW higher.

Tech tip: Finding The Right Tool for the Right Job

Each week our team in Ophir Optronics Solutions Ltd. receives requests to replace older or damaged laser power or energy meters and sensors. At the same time, we receive many items returned to us for re-calibration that we are unable to calibrate or repair.

Ophir has worked hard to educate our customers to reduce the laser damage caused by overheating or incorrect application to the wrong lasers; still, we realize that sometimes accidents happen.

In the article attached to this week’s blog post, we’ll discuss the best way to select the optimum power meter and sensor for your laser application using the Sensor Finder and Laser Fluence Calculator. In addition, you’ll be able to find a tutorial about how to avoid damaging your sensors:–measurement/knowledge-center/article/12141

How much of my sensor’s aperture should I fill?

In many laser measurement applications, the beam size can be controlled.

In such cases, how large should you make your beam? How much of the sensor’s aperture should the beam ideally fill?

The Importance of CO2 Laser Optimization

Every laser user, along with their superiors, wants the laser system to operate optimally. When these systems aren’t optimized, time and money is lost through lower cut speeds, increased dross on the edges of the cuts, and more frequent down-time due to maintenance.

Tech Tip: Minimizing Corrosion in Water-Cooled Sensors

Historically, corrosion in our sensors manifests as pitting corrosion in the anodized aluminum.
There are a number of factors that contribute to pitting corrosion including dissolved oxygen, chloride ions, more “noble”/cathodic metallic ions in solution, and excessive pH values (less than 4 or higher than 9). This is why we recommend neutral DI water, which maintains a healthy pH and removes chloride and metallic ions.
