  1. Understanding A Camera's Dynamic Range
    12/4/2017

    Since many camera manufacturers define dynamic range from a different point of view, a distinction should be made between the “dynamic range of an sCMOS, CMOS, or CCD image sensor,” “dynamic range of an analog-to-digital-conversion,” “usable dynamic range,” and “maximum dynamic range or SNR.” 

  2. 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. 

  3. Micromirror TIRF Microscopy: Technique And Applications
    11/29/2017

    Total internal reflection fluorescence (TIRF) microscopy is used to watch biological processes unfold in real time. Taking advantage of the ability to label individual molecules with different colors of fluorescent tags, TIRF microscopy lets scientists view the complex molecular assemblies that govern cellular processes.

  4. Building A Do-It-Yourself Atomic Force Microscope
    11/29/2017

    Atomic force microscopes (AFMs) are versatile tools for characterizing surfaces down to the subnanometer scale. Researchers can build their own AFMs for as little as $30,000 using off-the-shelf components such as nanopositioning stages.

  5. Technology Advances Lead To CMOS Sensor With Record Resolution
    11/29/2017

    In the past decade, CMOS sensors have emerged as the imaging technology of choice for many applications. Today, they are not only used in almost all cell phones and mobile devices, but are also commonly found in industrial and medical cameras.

  6. How Hexapod Motion Platforms Help Google Engineers Advance Cell Phone Cameras
    11/20/2017

    The engineers at Google have taken steps to optimize the motion and image stabilization algorithms in their Pixel 2 camera, which has been integrated with PI’s H-860 high-speed hexapod system that accurately simulates motion with 6 degrees of freedom and results in pinpoint-accurate crisp images.

  7. How To Make A Good Reflected Color Measurement
    11/17/2017

    When measuring reflection from an object, it is important to consider which type of reflection is dominant, and whether some or all the reflected light needs to be collected. This article discusses the best practices for making good reflected color measurements that can be used in a wide range of optical imaging applications.

  8. Thin-Film Optical Components For Use In Non-Linear Optical Systems
    11/16/2017

    Bio-imaging and detection techniques that use non-linear optical (NLO) phenomena have led to great advancements, such as super-resolution images, label-free visualization of naturally occurring biomolecules, and greater freedom for working with in-vivo samples. This white paper discusses the importance of choosing thin-film optical components for NLO systems to ensure optimal signal strength, resolution, and image quality.

  9. Thin-Film Interference Filters For LIDAR
    11/16/2017

    LIDAR is used for obstacle avoidance in autonomous vehicles, urban planning, security, infrastructure development, and other applications. This app note details how high-performance, ultra-narrowband interference filters improve LIDAR signal-to-noise ratios in specific applications.

  10. Understanding Interference Tilted Excitation (LITE) Microscopy
    11/15/2017

    When the detection of a cellular or subcellular structure requires a high NA detection objective, conventional fluorescence microscopy and light sheet fluorescence microscopy (LSFM) encounter challenges. Lateral interference tilted excitation (LITE) microscopy overcomes this problem.
