31. How Laser Light Is Different From Ordinary Light 9/21/2021

    The sun, stars and fire are natural sources of ordinary light. We recognize the light received by the human eye as white, whether it is the light of a lamp or the sun. However, we do not notice the spectrum of colors that make white, except through a prism by which light can be decomposed into different components.

32. How Often Should I Recalibrate My Laser Power Or Energy Detector? 7/27/2021

    Now that you got your hands on a brand-new Gentec-EO laser power or laser energy detector, you may be wondering "when will I have to let go of this awesome piece of technology for recalibration?" - or "is this older detector's calibration still valid?" Let's walk through detector calibration best practices. 

33. How To Know Your Laser Specifications So You Can Choose The Right Measurement Solution 7/26/2021

    If you want to measure the power of your laser, you need a detector and a power meter. There is a wide variety of detectors and power meters available, and not all of them are compatible with each other.

34. Measuring Laser Power With A Pyroelectric Detector: The Basics 7/9/2021

    This article discusses the various types of detectors and the differences between them, thus creating an understanding of why a pyroelectric detector is a great choice, providing advantages over other types of detectors.

35. Interfacing Options On PC For Power/Energy Detectors 7/9/2021

    Gentec-EO often fields questions about what interfacing options are available with their power and energy detectors. Interfacing here refers to the different methods by which you can communicate with the detector, may it be to read its output, change its settings or display the measurements in a user interface, etc.
