  • XRF

    O Series - Bowman

    The O Series combines high performance with a small x-ray spot size. This is made possible by the poly-capillary focusing optics system that replaces the collimator assembly installed in standard Bowman systems. The optics are designed to focus the x-rays coming from the tube exit window to a very small spot size (80μm FWHM) while retaining virtually 100% of the tube flux. So instead of attenuating the x-rays that can’t fit through the small apertures, as is the case with collimator systems, the poly-capillary optics assembly allows almost all of the x-rays from the tube to reach the sample. The result is much greater sensitivity for testing very small components or thin coatings. Shorter test times can achieve even better repeatability when comparing optics systems vs. a similar sized collimator.

  • Standard Electromagnetic Vibrator

    KD-9363-EM - King Design Industrial Co., Ltd.

    The purpose of vibration testing is to make a series of controllable vibration simulation in lab, no matter generated by natural or man-made vibration environment; such as waves, tidal flaps, wind, earthquake or rain and so on. It is to test if the product is capable of sustaining the vibration environment exerted from transporting or usage along its effective life cycle; and certify the standard of design & functional requirement of product. The value of vibration testing is to confirm the reliability of products and effectively screen out the bad products in factory; avoiding damages occurred at arrival; and to assess the failure analysis on the non-performing products; expecting to reach a high standard, high-reliability products. The vibration test stresses on the continuity and fatigue; and contributes to the understanding of product’s status under vibration circumstance in a normal environment; and avoids the product’s unpredictable damage caused under certain vibrating frequency for a long time.
