Monitor & Control Your Laser Power with Wi-Fi

You can now add any standard power sensor into your Wi-Fi network! Use the EA-1 Ethernet adapter with an off-the-shelf Ethernet to Wi-Fi adapter (not from Ophir).
That’s it.
Your sensor can now be controlled and measured remotely.
Now, at this point you might be wondering: “Why should I care if I can measure remotely with Wi-Fi?” Glad you asked. Here are 5 benefits to using Wi-Fi:

MKS’ Ophir® Business Unit Announces Calibrated Sensor for Measuring Very Low Power THz Sources

Andover, MA, May 8, 2017 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® RM9-THz Radiometer, a low noise, high sensitivity sensor for measuring low power levels of 50nW to 100mW from short pulse or CW lasers in the 0.7 to 10 THz wavelength range.

Is Your CO2 Laser Cutting Slowly?

It might be time to measure your laser power.

Laser cutting speed is a function of the material type, thickness, and laser power.

What’s the Lowest Power I can Measure with My (Thermopile) Laser Power Detector?

3 Watts.

Just kidding, obviously this is going to be your favorite answer: “It depends.”
And it doesn’t just depend on the type of sensor you have or the specs of that sensor.

Testing LED Luminaires on the Factory Floor

LED luminaires are being used more and more as a more efficient lighting source, among other applications.

As higher volume of LED luminaires must be pushed through the production line, factories struggle to keep quality control up to the same pace.  The traditional method of testing LED luminaires is using 6- to 10-foot integrating spheres, which simply cannot be used to test each unit at production speeds.

Measure Laser Spot Size & Power Density

If you read our article from last week, you’re already well aware that additive manufacturing can be used to create parts that are impossible to manufacture in any other way.

However, the quality and reliability of the additive manufacturing system depends on the spot size and power density of the laser.

Assuring Correct Metallurgy in Direct Laser Melting

Additive manufacturing has restructured prototyping, development, and advanced design of mechanical components. Direct Metal Laser Melting, also known as Selective Laser Sintering or 3D Metal Printing, is quickly becoming the standard for designs that cannot be fabricated with traditional metal removal techniques. To create consistent, strong structures using laser-based additive manufacturing processes that meet flyable DOD standards or FDA requirements, the metallurgy must be consistent. In addition, a laser beam of known dimension, power density, and focal spot location is required.

Laser Beam Optics Calculators

A laser is a complicated animal.

Whether you’re a lab researcher or an industrial worker, there are several parameters you might need to calculate, such as power density or ideal focus spot size.
We’ve recently added a few calculators to our website. I hope these calculators make your work just a little bit easier.
We have five laser optics calculators (so far):

Can You Really Measure Laser Beam Quality (M Squared) in Real Time?

M-Squared is arguably the single most important factor when determining the potential efficiency of your laser.

However, it can be a pain to measure.  Since the beam quality can be calculated only by taking several measurements along the laser beam caustic, you will typically need to move either the camera or laser source along its axis to get snapshots at different locations.

Here are two approaches you can use that actually DON’T move the camera or the laser:
