  1. 5 Common Applications Of Lasers In Electronics 12/28/2021

    Electronics, specifically lasers are more commonly used today than you may realize. Gentec EO explores a few common examples of laser applications in electronics in today's world.

  2. Understanding The Spectral Characteristics Of Your Detector 10/15/2021

    This application note explains how to understand the spectral characteristics of a Gentec-EO detector. In this text, you will find, among others, a clear definition for calibrated spectral range, range of available wavelengths, and spectral range.

  3. Calibration: Understanding The Process, The Techniques, And The Instruments 10/15/2021

    At Gentec-EO, we understand that the essence of our business has been delivering accuracy for over 45 years. There are no half measures: It either measures accurately, or it doesn’t. One of our company’s values is “rigorousness,” because our customers expect nothing less.

  4. Calibration Uncertainty Of Photo Detectors 10/15/2021

    The objective of this application note is to inform Gentec Electro-Optics’ distributors and clients about two aspects of photodetectors that are believed to cause some confusion and raise questions. 

  5. Measuring High Power Lasers With Low Power Detectors: A Cost Effective Solution 9/28/2021

    In industrial fiber laser applications like welding and soldering, it is rarely useful to measure the power of a laser beam before the end of the line since problems can occur after the point of measurement, at almost any point along the path that the light follows before it reaches the processed material.

  6. Measuring Multi-kW Welding Lasers On-Line 9/28/2021

    Over the past few decades, high power lasers have become ubiquitous in the automotive industry. Nowadays, they are used to process numerous vehicle parts. Laser welding is one of the techniques that have been considerably developed and improved over time. 

  7. Why Is The Surface Of My Detector Damaged? 9/21/2021

    So your laser power detector is supposed to be good up to 110W, and you damaged its surface with a 30W laser. Sound familiar? Why is this happening? Let’s find out.

  8. How To Measure A Large Laser Beam Profile 9/21/2021

    Laser beams tend to be very small when you want to look at the beam profile at their focal point or when they are collimated. It’s a challenge that we won’t cover here. What we will cover here is what to do when the beam doesn’t fit in your beam profiler sensor.

  9. Measuring Laser Power With A Pyroelectric Detector – The Basics of Energy Detectors 7/9/2020

    If you are involved with pulsed lasers at any level in research, product development, final test, process control, field service or laser safety, it is important to accurately measure the energy of your laser(s). In this technical paper, you will learn about the parameters that needed to consider when selecting and using a pyroelectric detector, and about the typical steps for making good energy measurements.

  10. Measuring Laser Power With A Thermopile Detector: The Basics of Power Detectors 7/9/2020

    If you work with CW or pulsed lasers, you need to accurately measure your laser power. The more you know about the measurement process, the better. This paper shares basic technical insights in the laser measurement field with the use of a thermopile detector.
