  1. Creating A Passive Laser Beam Analyzer Through A Haas Laser Technologies And Xenics Partnership

    High power CO2 lasers produce a beam of infrared light with wavelengths centering typically at 9.3 or 10.6 μm. Haas Laser Technologies, Inc. has developed a compact, all passive optical design laser beam analyzer for focused laser beams from a CO2 laser with wavelength range from 9.3 to 10.6 μm. In conjunction with a Fabry-Perot resonator and Xenics’ Gobi-640-GigE microbolometer camera, the new beam analyzer offers laser beam measurement and analysis for continuous-wave (CW) as well as pulsed lasers.

  2. Seeing The Light: Sizing Up Universal Light Guides For Medical Instruments

    The Universal Light Guide is a workhorse of medical diagnostics that enables the high performance of high-end medical equipment such as endoscopes, the instruments of discovery that enable physicians to see, detect, diagnose and operate on parts of the body that are usually shielded from light.

  3. Automation And Microscopy: Faster Test And Measurement

    Nanotechnology uses the concept that constant velocity will get you to the destination faster than constantly stopped traffic. One technique puts this concept into practice via a fast nano-focus device based on a piezo-ceramic actuator embedded in a flexure guided lens positioning mechanism.

  4. Choosing The Best Prototyping Process For Your Project

    This Proto Labs white paper demonstrates the importance of selecting the best prototyping process for every project, including the pros and cons of each process, attribute comparisons, and impact on time-to-market.

  5. Six Ways To Cut Machining Costs

    Proto Labs has been in the machining business since 1999, and in that time, they’ve learned a thing or two about the intricacies of the CNC machining process. This document contains a compilation of their shared knowledge as it relates to reducing your overall costs by trimming machine expenses.

  6. Design Considerations For The Visual Appearance Of Injection-Molded Plastic Parts

    The success of the products we design can often be affected by their visual appearance.

  7. Designing For Moldability: Undercuts And Through-Holes

    With this white paper, designers can address the challenges of parts that have indentations, through-holes, and other features that don’t point straight up or down.

  8. 5 Design Considerations To Improve Success Rate Of Multi-Cavity Molds

    It is important to recognize that parts behave differently in multi-cavity tooling unless tweaks are made to the part, the process, or material.  This article talks about how to use adjustments such as holding the gate, employing side-actions or pick-outs, utilizing family molds, and using easy-flow materials to successfully upgrade single cavity molds to multi-cavity molds.

  9. High-Speed Imaging Uncovers The Invisible With Schlieren Techniques

    Although schlieren imaging - a noninvasive testing method - can deliver detailed images of highly dynamic processes, obtaining high-quality data requires choosing the best high-speed camera for the application and careful optimization of the optical setup.

  10. Q&A With SPIE CEO Dr. Eugene Arthurs

    In July, SPIE CEO Dr. Eugene Arthurs announced his intent to retire effective on Jan. 19, 2018. Recently, Dr, Arthurs graciously made time to reflect on his career at SPIE, as well as his and the organization’s future, with Photonics Online.
