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: http://www.ophiropt.com/laser-measurement-instruments/laser-power-energy-meters/knowledge-center/tech-tips/right-tool

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?

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.

How can I communicate with an Ophir laser Power Meter using a Linux machine?

Let’s say the computers used in your laser environment happen to use Linux as an operating system, and you want to integrate the laser measurements from an Ophir laser power meter into your Linux computer system, preferably via USB communication. Here’s how you can make it happen quickly and easily:

PEAK POWER VS. AVERAGE POWER- MASTER IT & CALCULATE IT

If you always wanted to learn how to measure the real pulse temporal shape of your laser – and use it to calculate the peak power – this is the perfect blog post for you.

Since power is a measure of how much energy is transferred in a unit of time, this is the prevalent parameter when it comes to lasers.  However, if the laser is pulsed, things start getting complicated.

Why does measuring your laser beam help you maintain quality processes?

Much like a light ball that degrades over time, a laser beam at the work surface has to be maintained and preserved in order to keep it’s high & precise performance.

Why does measuring your laser beam help you maintain quality processes?

The only hand-held Ophir meter that measures laser exposure/dosage

Usually, when discussing laser measurements, we often refer to the power or energy of the laser.

Sometimes though, we need to measure the total energy Exposure the total sum of the laser energy deposited over a set amount of time.
