  1. New Tool Measures 4 Surface Appearance Quality Conditions Simultaneously
    1/18/2018

    If surface appearance quality is critical to your product, learn about a new manufacturing-friendly tool that allows you to establish numerical standards for and measure four conditions of surface quality: gloss, haze, image clarity, and BRDF including Canon’s new parameter “Scattering C20, C60.” This new parameter goes beyond IC and DOI to enable measure of non-glossy surfaces such as textured surfaces, matte paint, and matte paper. 

  2. Optical Interconnects For Data Centers – Lighting The Cloud
    1/16/2018

    The demand for storage and data transfer capacity has increased dramatically as data storage and computing resources have moved into the cloud over the last decade. The need to constantly access and transfer data to and from, as well as within, data centers has placed a huge load on the interconnects connecting the backplanes of data servers. This, in turn, is expanding the role and capability of optical interconnects and drives with in the cloud.

  3. Glass-Sealed Connectors Help Increase The Longevity And Reliability Of Medical Devices
    1/9/2018

    Glass-to-metal sealing technology, already used in other harsh-environment applications - such as aviation, aerospace, and automotive safety - has emerged as an ideal solution in the development and manufacture of medical connectors. 

  4. Visualizing Growth In Hyperspectral Imaging: A Q&A With TruTag CTO Hod Finkelstein
    12/11/2017

    Dr. Finkelstein discussed with Photonics Online how his experience in the medtech and RF industries helped inform decisions when creating new HSI technologies. He offered insight into maintaining balance in the growth of both optical and data processing technologies for HSI, and discussed development of TruTag’s Prism Award-winning hyperspectral imaging solution.

  5. Frequently Asked Questions: Optical Thin Film Filters
    12/11/2017

    This article answers an array of frequently asked questions about optical thin film filters. It provides in-depth information on what they are, how they are created, how they perform, and what to look for when selecting an optical thin film filter supplier.

  6. Revealing Cotton’s Fiber Quality With Hyperspectral Imaging
    12/5/2017

    Traditionally, hyperspectral imaging systems or cameras have been bulky, heavy, and costly. However, recent technological advances are changing that and opening the door to new opportunities in hyperspectral imaging.

  7. Understanding A Camera’s Resolution
    12/4/2017

    The resolution of an image sensor describes the total number of pixels that can be used to detect an image. From the standpoint of the image sensor, it is sufficient to count the number and describe it usually as the product of the horizontal number of pixels times the vertical number of pixels.

  8. 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.” 

  9. 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.

  10. 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.
