All products specifications

Feature

  • Produces high contrast and resolution in both the center and corners.
  • Virtually no TV distortion of entire image area.
  • Able to adjust the magnification to match with the pixel size of the camera
  • Lenses are designed with an optical magnification that is ideal for over 5 megapixels
  • Distortion free lenses of less than 0.02%. TV distortion is limited to 0.25% on the entire image area even when used with a 5 megapixel camera

  • Telecentric Optical System

    In a telecentric optical system, there is no change in magnification when focusing. Thus, the magnification remains constant at different working distances. Similarly, the movement of an object also does not change the magnification, which makes a telecentric lens ideal for measuring objects with high accuracy.
    In a telecentric optical system, the chief rays are parallel to the optical axis. As a result, the aperture becomes greater as the magnification is fixed by the focusing rays. This means that the F-number on a telecentric lens tends to be larger when compared to a standard megapixel lens.
