 &amp;nbsp; 
 Main features 
 
 
 
 
 
 Relative illumination reaches up to above 90% 
 
 
   
 
 
 
 
   In general, the illumination of the peripheral area of the image is determined by &quot;relative illumination&quot; and &quot;chief ray angle (CRA)&quot;. CF-ZA-1S series adopts the original optical design of Fuji film with the relative illumination up to above 90%* (lens monomer) and supports 1.1&quot; type large sensor, and restrains CRA below 5°. Because the two are relatively balanced to each other, the clear and bright image can be obtained from the peripheral area.   * When the F4 F-Stop is used more frequently by users.  
  In general, in order to improve the difference between light and shade in the center and peripheral area, the correction treatment of the image can only highlight the &quot;noise&quot; but cannot obtain good image, while CF-ZA-1S series has no need to correct illumination and realizes uniform illumination including the peripheral area, thus the high-quality image with low noise can be obtained. It is most applicable to the inspection demanding higher reliability.  
 
 
 
  &amp;lt;Real image without correction treatment&amp;gt;&amp;nbsp;  
 
 
   
   
 
 
  CRA is macro lens&amp;nbsp;  
  &amp;nbsp;CF-ZA-1S series  
 
 
   
   
 
 
 
 &amp;nbsp; 
 
 
 
 
  Original high-resolution performance of Fujinon lens   &quot;4D High Resolution&quot;  
 
   
 
 
 
 &amp;nbsp; 
  &quot;4D High Resolution&quot; keeps uniform high resolution   
  &amp;nbsp;from the image center to peripheral area and can restrain the decline of resolution caused by shooting distance or F-Stop, which is the original high-resolution performance of Fujinon lens. Therefore, the high-resolution image can be obtained  
  under various setting and photographic conditions.  
  Supporting 1.1&quot; type sensor and 3.45μm pixel pitch (equivalent to 12 mega-pixel) makes the most use of camera performance. Especially, it is most applicable to IMX253 (1.1&quot; type) and IMX255 (1&quot; type).  
  The lens supports next generation sensors which are becoming more sensitive. It is good for 1.1&quot; type sensor and 2.5μm pixel (equivalent to 23 mega-pixel).  
  Restrain unilateral bokeh and single flaw through high-precision assembly technology and original detector.  
 &amp;nbsp; 
 &amp;nbsp; 
 
 
 
 
  Adopt the FUJIFILM&#039;s original mechanical structure design of   
  &quot;vibration-resistance and impact-resistance&quot;&amp;nbsp;  
 
  &amp;nbsp; &amp;nbsp;&amp;nbsp; 
 
 
 
 &amp;nbsp; 
  Conduct strict vibration test according to JIS C 60068-2-6* 1&amp;nbsp;and keep high resolution prior to and after the test.  
  Under the circumstance that the robot vision and 3D scanning, etc. are hit, even by maximum a 10G* 2&amp;nbsp;hit, the optical axis variation   (picture dislocation) is only below 10μm.&amp;nbsp;  
  Without excessive use of glue and by adoption of the company&#039;s&amp;nbsp;original mechanical structure* 3, the degradation caused by humidity,&amp;nbsp;heat and long lasting will not occur.  
  The performance of &quot;vibration-resistance and impact-resistance&quot; is secured even though the iris can be adjusted. These features makes operation easier.  
  *1: [According to JIS C 60068-2-6], vibration frequency 10-60Hz (amplitude 0.75mm), vibration frequency 60-500Hz (acceleration 100m/S2), and scanning round 50 cycle   *2: Applicable value of hit G varies from model to model   *3: The company&#039;s original technology that has been patented  
 
 
 
 
 Support large sensor and realize compact outer diameter φ39㎜ at the same time 
 
 
 High convenience and reliability 
 
 
 
 
  Compact design of outer diameter φ39㎜ (CF8ZA-1S: outer diameter φ54㎜) contributes to saving space.  
  &amp;nbsp;   
 &amp;nbsp;Retrofit CF-ZA series on the Machine Vision camera that supports large sensor  
 
  By adopting internal mechanical focus, the overall length of lens will not change when focused  
  Provided with 3 positioning holes for fixation of the Iris and focusing on lens body and the positioning hole can be selected according to setting conditions.  
  Having a indication sign on the lens that shows the optimal focus position when the subject is 50cm apart helps you to detect the flange back dislocation effectively.  
  The &quot;anti-separation structure&quot; is implemented on the knob of the Iris and focusing screw even if it is shaken violently, the screw will not fall off.  
  When manufactured, the optical performance results of each lens are managed by the factory.   As the tool for FUJIFILM quality management,   the lens cone of each lens is printed with QR code.

                 The Impact of Shocks and Vibrations to Industrial Imaging Systems 
 &amp;nbsp; 
 
 &amp;nbsp; 
 &amp;nbsp; 
   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.  
  Most industrial machine vision solutions utilize 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&amp;nbsp;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&amp;nbsp;  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 color 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&amp;nbsp; Fujinon HF-12M &amp;nbsp;series, as well as the lenses of the&amp;nbsp; HF-5M series &amp;nbsp;with&amp;nbsp;  
  6 and 50 mm focal length, withstand the shocks and&amp;nbsp;  vibrations showing a shift of the optical axis of just&amp;nbsp;between 4 and 10 µm.  
   
  This is enabled by the Fujinon Anti-Shock &amp;amp; Vibration design, an elastic and patent pending fixation of the internal lens arrangement.&amp;nbsp;  
  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 &amp;amp; Vibration design of the Fujinon lenses, however, minimizes 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.
