  1. Motion Control Advances For Laser Micromachining And Microprocessing

    Many laser micromachining and micro processing engineers face challenges of delivering laser pulses to a workpiece with a high degree of accuracy and repeatability, and developing a strong human machine interface (HMI) software through CAD/CAM post processing, motion profile generation, user interface and host programming, motion programming, laser control, and real-time IO control. This article discusses how these issues can now be solved with PI’s motion/CNC controller technologies that are designed to reduce complexity, and allow for faster time-to-market while improving the process accuracy.

  2. Advanced Camera Manufacturing And Lens Alignment Enabled By Compact 6-Axis Micro-Robotic Hexapod Systems

    Hexapod micro-motion robot technologies provide all six degrees of freedom in a stiff, compact, and high-precision structure. This app note discusses how the functionality enabled by a compact 6-axis micro-robotic hexapod system provides precise manufacturing and lens alignment in advanced cameras.

  3. New Tool Measures 4 Surface Appearance Quality Conditions Simultaneously

    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. 

  4. Optical Interconnects For Data Centers – Lighting The Cloud

    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.

  5. Glass-Sealed Connectors Help Increase The Longevity And Reliability Of Medical Devices

    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. 

  6. Visualizing Growth In Hyperspectral Imaging: A Q&A With TruTag CTO Hod Finkelstein

    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.

  7. Frequently Asked Questions: Optical Thin Film Filters

    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.

  8. Revealing Cotton’s Fiber Quality With Hyperspectral Imaging

    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.

  9. Understanding A Camera’s Resolution

    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.

  10. Understanding A Camera's Dynamic Range

    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.”
