Core functions and configurations

• Two standard visual indicators can be selected simultaneously
  

  The target meets the requirements of GB 39552 and EN ISO 12312, and adopts a green band peak filter with a design close to the visual transfer function. The brightness and angle of the target can be adjusted and set through wireless control;
  

  ANSI Z87 visual standard lens clarity and refractive power testing;
  

  It can meet the testing requirements of various transmittance lenses, finished glasses, goggles, protective masks, etc.
• 24x undistorted telescope
  

  Excellent telescope design ensures that the visual target is clear and visible (without distortion), while the size of the visual target matches the field of view of the telescope well. Maximize the restoration of clear visual targets.
• Camera acquisition scheme
  

  Minimize subjective errors in human observation. Cooperate with MD software control to save and match the observed visual target image with the corresponding top focus data. Easy to make comparative judgments in subtle changes and strive for accurate testing.
• Measurable parameters
  

  球镜度 / Spherical power

  散光度 / Astigmatic power

  棱镜互差 / Prism imbalance

Test fixtures and software

• Uncut lens testing fixture
  

  The lens holder is a quick detachable structure that can be quickly replaced with a lens holder. The synchronous structure and four free pivot points can be adjusted in any position. Supports almost any size and curvature of lens; Support integrated wind mirror testing.
• Finished Sunglasses Testing
  

  A special fixture simulated by a humanoid head model that can meet the testing needs of both adult and children's finished sunglasses, supporting quick left and right eye switching between 64mm and 54mm. And the simulated forehead support structure supports the testing of protective masks.
• Lens Optical Quality Special Testing MD Software
  

  Control the camera through synchronized steps, wireless backlight adjustment, and visual target angle rotation. Automatically convert lens sphericity, prism power, and prism power; And perform prism mutual difference calculation. Automatically determine whether the test data has passed according to standard requirements, and there is a red font prompt for items that have not passed. And it has the ability to save and import test data and images for easy product quality tracking. The report output function meets multiple standard requirements simultaneously.
