  1. Achieving Standardized Measurements With BeamWatch AM
    12/1/2017

    The BeamWatch AM is Ophir-Spiricon’s beam monitoring system designed specifically for use in the additive manufacturing industry to provide non-interfering real-time beam measurement at the location of the working plane. This white paper delivers a comparison of results with those from the NanoScan 2, a widely-accepted scanning-slit technology, and demonstrates that the BeamWatch AM can achieve ISO-compliant measurements when correctly used.

  2. How Ophir-Spiricon Determines The Dynamic Range Of Laser Measurement Products
    7/13/2017

    This article explains the importance of understanding and stating a dynamic range correctly. This paper also provides insight on how Ophir-Spiricon, a global leader in precision infrared optics and photonics instrumentation, determines its products’ dynamic range properly.

  3. Meeting Optical Needs For Drones
    7/13/2017

    UAV optics with higher MTF values and lower F# are used more frequently as detectors become larger in size and smaller in pixel size to maximize imaging performance. This article describes the  improvement of lens quality with higher performance levels to ensure that UAVs operate with the highest performance possible.

  4. How To Make Laser Welding And Cutting Affordable And Sustainable

  5. Laser Beam Diagnostics In GHz Applications
    6/5/2017

    It usually is insufficient to rely on one standard measurement technology when working with applications in exotic optical wavelengths and unusually low average powers. This white paper goes through an example of calculating many laser beam diagnostics within high GHz applications.

  6. What To Expect In A Laser Profiling Demonstration
    6/5/2017

    When asking someone for a laser beam profiling demonstration, it is important to understand what you are asking for and what you should expect. This white paper covers the steps needed to take to set up a demonstration, and what is expected of each party.

  7. Working In The Basement: Measuring Signals Below The Noise Floor With A Lock-In Amplifier
    6/5/2017

    This article presents the advantages of using lock-in amplifiers for measuring signals below the noise floor, how they work, and available devices from Ophir.

  8. Sensor Fusion Enables Comprehensive Analysis Of Laser Processing In Additive Manufacturing
    6/5/2017

    This white paper discusses sensor fusion, a process that merges data from numerous sensors to create a more complete understanding of the laser-enabled process.

  9. Testing High-Volume LED Luminaire Builds
    4/20/2017

    The lower operating costs of LED luminaires drive growing demand for them in consumer and commercial markets. This increased demand requires an adaptation to improved quality testing methods that can provide superior measurements and not slow down the process of production. 

  10. Assuring Correct Metallurgy In Direct Laser Melting
    4/20/2017

    High quality 3D laser printed processes require a laser that delivers the correct amount of power that is distributed correctly and focused at the correct location. To ensure consistent and structurally sound parts and correct metallurgy, the right parameters should be directly measured before and after any critical part is made in direct laser sintering. This application note presents how Ophir Optics’ BeamCheck system is able to measure critical laser beam parameters for laser-based additive manufacturing.
