How to Use the StarLite with Your PC. And Why

When we released our newest laser power meter – the StarLite – last year, we wanted it to be as simple as it could be.  Yes, that means there would be fewer features, but that was the point.  A simple meter at an affordable price. The main goals were:

Do You Know the Power Density of Your Laser?

Lasers can be dangerous. For you, for your workspace, and for your measurement equipment. Some people assume high power is the problem and low power is safe.  This isn’t necessarily the case, though.  What you really want to look at is the power (or energy) density of the laser.

Water Cooled Sensors: Things to Look Out For

Water cooled sensors are commonly used when measuring laser beams of more than a few hundred watts. In this video, you will learn about some critical issues you need to consider when using water cooling, such as water temperature, water flow rate, and corrosion prevention.

OEM Laser Energy Sensors

The beauty of integrating an OEM sensor into your laser system is you get to call the shots. What matters to you the most?  Accuracy?  Size?  Output type?

Here’s How Klaus Hansen Measures his Laser

We are proud to announce that Klaus Hansen is the winner of our Facebook beam profiling image contest.  He entered the picture below – “advanced beam shaping for laser cutting and welding.”   Want to know how and why he profiles his laser systems?  Want to find out the trick he uses to make laser…

What Is an ND Filter? How You Should (and Shouldn’t) Use It

Short answer: A neutral density attenuator. Meaning? Long(er) answer: A filter that attenuates all wavelengths equally.  Well, that’s an ideal ND filter, anyway.  A real one affects different wavelength differently, but the difference is kept to a minimum.

Extending the Power Range of a Photodiode Laser Sensor

If you want to measure low laser power, you’ll likely use a photodiode sensor. Now imagine your laser varies in power, or perhaps you have several lasers you need to measure, with different power outputs.  Of course, ideally you’d like to measure them all with the same sensor.  But can you?

A Photodiode Laser Sensor for Every Wavelength

If you are measuring very low powers, you’ll want a photodiode power sensor. These come in various models, with physically different detectors. Some are made from Silicon, some are Germanium, etc. Different detectors act differently at different wavelengths. For example

Measuring Very High Power Laser Beams: Challenges and Solutions

Laser beams with powers of many tens of Kilowatts are becoming more and more common in today’s applications, industrial as well as research. This video will discuss the technical challenges in measuring such lasers, and will show you a range of solutions now available from Ophir for measuring up to 100KW — safely, and accurately.

Laser Power Meter and Sensor Compatibility

Ophir laser power sensors have a smart head which allows for complete plug-and-play, where any sensor works with any meter.  The smart head stores all the sensor settings (such as calibration information) so they are saved even when using a different power meter.

Wavelength Guide for Thermal Laser Power Sensors

Thermal laser power sensors have various coatings used to absorb the laser heat.  Each coating has its own absorption per wavelength graph which means that each coating also has its own range of calibrated wavelengths.

How to Measure Laser Exposure

Usually, laser measurement focuses on power or energy, (or both). In some cases, however, the total energy exposure needs to be measured. Exposure means the sum of all the energy that hits the target (be it metal, electronic wafer, or human skin). Two common cases where exposure is key are medical lasers and photolithography. In…
