Manage multiple suppliers using one unbiased testing algorithm and catch issues earlier in your supply chain. Imatest IT software allows for the integration of key Imatest Master and Image Sensor (IS) module functionality into your custom testing programs. Image focus (focus adjustment) is maintained at all focal lengths (zoom-in) and constant distance from object by means of back focal distance adjustment.Imatest Industrial Testing (IT) enables rapid production line testing and optimal quality control in manufacturing environments. If necessary optimize by alternating with optical focus adjustment.Ģ、With unchanged optical focus adjustment and shortest focal length adjust the red and blue pick-up tube until optimum focus is achieved. With shortest focal length and divergent focus adjust the pick-up tube in W-channel until optimum focus is achieved.

Set optical focus at greatest focal length.

With the aid of a low transmission filter and by means of low level lighting make sure that the camera is not over modulated with the aperture in the open position.Ī) Optical focus: Adjust focus of zoom lens at greatest focal length.ī) Back focal distance (lens): Adjust focus at shortest focal length by regulating lens mechanically with adjustment screw and optimize alternatively with a).Ĭ) Back focal distance (pick-up tubes): If focus varies from channel to channel between greatest and shortest focal length, the individual pick-up tubes must be adjusted mechanically in the optical axis.ġ、Select white channel. It shows a 36 sector Siemens star on a white background.

The YE0120 test chart is designed for the adjustment of camera lenses and checking back focal distance.
