Optical lens is essential for machine vision system components, directly affect the image quality of the pros and cons of algorithm implementation and effectiveness. Also off the right lens for election to reduce the cost of machine vision systems, is the only way to industrial prosperity. Many specifications optical lens, and sometimes can not help but feel dizzy. Optical lens from focal length lens can be divided into short, medium telephoto lens, telephoto lens; points from a wide field of view, standard, telephoto lens; structure of sub-prime lens with fixed aperture, fixed focal manual iris lens , fixed focus auto iris lens, manual zoom, auto zoom, auto-iris power zoom lens, electric three-variable (aperture, focal length, focus can be changed) lenses. According to our experience of using Russia's optical lens is very cheap.

   Notes

  1.   Above molding conditions are those used in the molding test for our optical lens mold.
  2.   Since TOPAS®5013LS-01 is a high flow material, it’s evaluation is to be started at lower mold temperature, lower
       molding pressure and low injection speed.

 Notes concerning injection mold of TOPAS® 5013LS-01
   q      Do not excessively lower the screw rotation speed.
           Ø Low rotation speeds may not assure high-transparency molded parts. 100 to 150 rpm is recommended
              for popular optical screws, which may vary depends on screw design.

       l Example of a molded product with 30rpm Screw rotation speed.


                                               ←Same splay mark can be observed over the surface at the
                                                flow end of the 70mm2,1mmt flat-plate test piece.
                                                  (Gel have been generated during plasticization.)



   q      Control the mold temperature at between 105 to115 deg C by actual measurement.
           Ø Highly transparent molded products may be impossible below 100 deg C.
           Ø Cooling time will take longer at over 120 deg C.


   q      Seal and purge the hopper with Nitrogen.
           Ø Prolong molding may cause burns and black spots.
              Also short-time molding may discolor molding products yellow a little without Nitrogen purge & seal.

   q      Clean the screw as often as possible when replacing the material.
           Ø Clean start after cleaning the screw is recommended to prevent contamination.
           Ø When screw cleaning is impossible, it is recommended to purge the screw once using a highly viscous
              COC material such as TOPAS®6013S-04
