FUJIFILM Optical Devices Europe GmbH news
Industrial imaging systems are frequently subject to strong accelerations, shocks, and vibrations. This is especially true for mobile systems, like robot-guided 3D scanners, but also for fixed installations. Fujifilm has investigated the impact of shocks and vibrations on industrial fixed focal lenses via a dedicated test procedure. In many cases, the procedure leads to a significant reduction of the resolution and to a shift of the optical axis. However, the intensity of the effects depends heavily on the mechanical design of a camera lens—a widely underestimated aspect at the selection of fixed focal lenses. Modern robot arms are so powerful they can move major loads with a multiple of the gravitational acceleration (unit G, 1 G = 9.81 m/s²). Robot-guided machine vision systems, as they are used with welding and assembly robots as well as with 3D scanning stations, need to withstand such accelerations. Additionally, they are exposed to the vibrations at the tip of the robot arms just like camera-lens setups at large machines with rotating elements, e.g. in large offset printing systems.Fujifilm has developed a testing procedure for such lenses to measure their robustness against shocks and vibrations. Shock testing on machine vision cameras Most industrial machine vision solutions utilise industrial cameras and c-mount lenses with fixed focal length, which need to provide constant image quality irrespective of harsh conditions. Therefore, Fujifilm has developed a testing procedure for such lenses to measure their robustness against shocks and vibrations. At first, 10 G shocks impact the lenses from 6 different directions orthogonal to the optical axis. Next, a special vibrating table exposes the lenses to various sinusoidal vibrations according to IEC 60068-2-6 (up to 500 Hz and 100 m/s²). Finally, the shock test is repeated. The results show a shift in the optical axis of a conventional lens by up to 26 µm which corresponds to approx. 7 pixels at Sony Pregius sensors of the second generation. Their resolution power, measured using a contrast chart, deteriorates dramatically (see false colour rendering). For most machine vision applications, where fast accelerations and strong vibrations may occur, these lenses are not suitable. On the other hand, all lenses of the Fujinon HF-12M series, as well as the lenses of the HF-5M series with 6 and 50 mm focal length, withstand the shocks and vibrations showing a shift of the optical axis of just between 4 and 10 µm. This is enabled by the Fujinon Anti-Shock & Vibration design, an elastic and patent pending fixation of the internal lens arrangement.The Anti-Shock & Vibration design of the Fujinon lenses minimises the dependency on adhesives and ensures a constant performance and image quality in the long run. Towards high image quality At conventional camera objectives, the lenses are fixed with adhesives, which does not withstand shocks and vibrations plus it is sensitive to changes in humidity and temperature. The Anti-Shock & Vibration design of the Fujinon lenses, however, minimises the dependency on adhesives and ensures a constant performance and image quality in the long run. Beyond the optical format, resolution power, and focal length, developers of mechanically stressed imaging systems should consider the robustness of their camera objectives against shocks and vibrations. The following lenses are already equipped with the Fujinon Anti-Shock & Vibration design: HF-12M series for pixel sizes from 2.1 µm and sensors up to 1“ HF-5M series for pixel sizes from 3.45 µm and sensors up to 1.1 (focal length: 6 and 50 mm)
FUJIFILM Optical Devices Europe GmbH is responsible at its Kleve location for the sales, marketing and servicing of professional FUJINON lenses for TV and film productions, CCTV and Machine Vision as well as FUJINON Binoculars in Europe, the Middle East and in Africa. Security and industrail image processing For many years, FUJINON has been creating award-winning lenses. It develops and produces innovative, cutting-edge solutions for almost every application in the entertainment industry, security systems, and industrial image processing. The professional lenses for TV and film productions redefine the limits of high resolution, high contrast ratio, and high dynamic range. They create the pin-sharp TV pictures and help camera operator’s film stunning and powerful scenes. Precise machine vision lenses Thanks to the megapixel-zoom and megapixel-varifocal lenses, CCTV systems are featuring high resolution. The steadily growing portfolio of precise machine vision lenses for industrial image processing ensures minimal distortion for highest image quality, even under harsh conditions. FUJINON binoculars are known throughout the world. In particular, the FUJINON binoculars are very much appreciated by users in professional and semi-professional areas.
As part of a company-wide reorientation and a consistent growth strategy, FUJIFILM Corporation and FUJIFILM Europe B.V., Tilburg (Netherlands) have decided to concentrate their European Optical Devices division from 1 October 2017 into FUJIFILM Optical Devices Europe GmbH, Fujistrasse 1, 47533 Kleve, Germany. FUJIFILM will manage the area of optical devices Europe-wide from this company. New FUJIFILM management The management of FUJIFILM Optical Devices Europe GmbH is being taken over by the existing Senior Vice President Homare Kai and Christopher Brawley, Managing Director of FUJIFILM Electronic Imaging Europe GmbH. “The new structure enables FUJIFILM to respond more efficiently to the requirements in this market segment. A high speed and flexible adaptation to market requirements are required for success in this demanding field of business”, explains Christopher Brawley, clarifying the reasons for the reorganisation. Maintaining company growth Already since 2012, the optical business and the electronic imaging business have been carried out in the FUJIFILM company headquarters in Japan by a single business area. So that they can take full advantage these synergies in Europe as well, the two business areas are now concentrated at the Kleve site. The changes are intended to contribute to maintaining the growth of the company. In addition, synergies are expected through the closer connection to FUJIFILM Recording Media GmbH and FUJIFILM Electronic Imaging Europe GmbH, which have already been operating successfully from Kleve for many years.
