  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. Quality Assurance In Additive Production 3/17/2020

    Whether in research or in production, the laser parameters must be checked regularly. For this purpose, Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT generally turns to the Ophir BeamWatch AM, which measures the laser beam without contact, is compact enough to be used inside the production chamber, and delivers measurement results quickly. This case study covers the full story.

  8. Measuring Average Power Of Pulsed Lasers With Photodiodes 3/17/2020

    Recent development in VCSELs for applications in remote sensing, require measurement of average power during pulsed operation. When measuring average power of pulsed lasers, another mechanism may also affect the linearity of the photodiode. In this article we review this mechanism.

  9. ISO Compliance Of Non-Contact, Real-Time Beam Analysis 8/1/2019

    To deliver continuously high product quality, the key parameters of laser beams in production applications must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology, the BeamWatch, based on the Rayleigh scattering. 

  10. Battle Axe vs. Scalpel: How To Work With High Power Density Lasers 8/1/2019

    In this Q&A article, Mark Gitin, Senior VP and GM of the Light & Motion Division of MKS Instruments, and Christian Dini, Director Global Business Development, Ophir, discuss the use of reliable laser beam measurement technology that can help with the process of laser optimization.
