  1. Measuring Very Low Power IR Lasers With The RM9 Radiometer System 7/30/2020

    There are two main technologies - thermal and photodiode - that are commonly used for measuring laser beam powers. But what if you need to measure very low power laser beams with wavelengths in the mid or far IR region. This article discusses a solution to fill this gap with the RM9 radiometer system.

  2. Centauri High End Power/Energy Meter Experience – Now At The Tip Of Your Fingers! 7/30/2020

    Ophir Photonics introduces the Centauri Web simulator. Check out this article to learn more on how the simulator can allow you to experience most of the Centauri power/energy meter's functionalities.

  3. Characterizing A Laser Used In Metal Additive Manufacturing Equipment 7/30/2020

    In this application note, a developer of power-bed additive manufacturing systems needed a beam profiling system that could be used by their field technicians for setup and maintenance of customers’ lasers. The bulky water-cooled system they had been using was costly, and long lead times for sale and repair were unreasonable. Moving to a BeamGage® based system made setup quick and finding the focal spot location easy.

  4. Ophir Power/Energy Meter Calibration Procedure And Traceability/Error Analysis 7/24/2020

    This white paper discusses the interpretation and basis for stated measurement accuracy of Ophir Laser Power/Energy meters.

  5. Laser Forensics: The Invisible, Revealed And Measured 7/6/2020

    According to the developers at Scanovis, brushes, powder and chemicals will soon be tools of the past for securing evidence at crime scenes. The company has developed a laser-based solution that, among other things, uses IR laser radiation to detect fingerprints at the scene of a crime, quickly making them visible in a 3D scan and recording them digitally. Decisive factors for this technological breakthrough are the precision of the results delivered by the laser scanner and the easy handling of the system. But how to adjust the optics of a system using a low power laser in the mid-infrared spectrum? Working together with Ophir's measurement experts, the company was able to combine different measurement methods to this end.

  6. Keeping Your Additive Manufacturing Laser In Spec 7/6/2020

    Additive manufacturing allows for more customized parts using more specialized materials, and will eventually create a more localized, rapid, and agile distribution network. This white paper discusses important laser performance characteristics, how to measure them, and how to keep the laser in spec.

  7. Fighting Viruses: UV-C LED - Will All The Research Soon Pay Off? 7/6/2020

    The world remains in a continuing state of uncertainty due to the new COVID-19 coronavirus. Face masks and disinfectants are selling very well. Disinfection with UV light could offer a way of disinfecting larger areas without the use of chemical disinfectants, especially in hospitals where patients are being treated.

  8. Are You Safe At A Laser Light Show? 5/12/2020

    The assessment of laser beam exposure used for entertainment applications is a challenging undertaking. Both the emission and the environment pose particular obstacles to persons with the responsibility of ensuring emissions are below the permissible exposure limits. This article discusses how use of Ophir’s BC20 detector is able to offer significant improvements in measurements quality over traditional laser power detectors intended for CW beams.

  9. Using Ophir’s IS1.5VIS-FPD-800 Multi-Functional Integrating Sphere For VCSEL Measurements 5/12/2020

    Ophir’s IS1.5-VIS-FPD-800 multi-functional sensor for measuring VCSELs includes precision photodiodes for calibrated average power measurements, fast measurements for pulse shape characterization on an oscilloscope, and an SMA fiber optic adapter for easy connection to a spectrometer.

  10. Choosing The Optimal FluxGage Model For Your Application 3/18/2020

    To select the Ophir FluxGage model that will best suit your needs, first consider two questions: What size are the luminaires that you plan to measure (what is their light emitting surface size), and what is their expected luminous flux? The answers to these questions will help you find the right solution.
