Schneider Industrial 12k High Resolution Lenses

Lenses for high-resolution line scan

12k_large1 schneider

The line scan image capture method is useful and efficient for many web and other surface inspection applications. When choosing an appropriate camera, correct lens selection is critical to achieving the desired system performance. The size of the linear array sensor in the camera determines the minimum required image circle of the lens and the size of the sensor’s pixels determines a particular optical imaging resolution. The desired object resolution defines the necessary magnification ratio for the optical system. These application specific parameters let you choose the most suitable lens to meet all requirements with respect to image size and quality.

Today’s high-performance lenses must follow the technology trend toward smaller pixel sizes and increased sensor resolution. This typically results in larger array sizes and more stringent requirements concerning MTF (Modulation Transfer Function).

Macro-Symmar lenses are designed for industrial machine vision applications and satisfy even the most stringent requirements of 12K line scan applications. These lenses cover a magnification ratio range from 0.33X to 2.0X by using the lens either in standard or retro position. An extension tube together with a special helical mount is used to adjust the focus precisely. Focus as well as iris adjustment are lockable to ensure system stability even in the presence of vibration. A tilt alignment tool can be used to adjust the sensor’s orientation with respect to the optical axis of the lens. The V-mount interface allows alignment of the lens for the best average azimuth position with respect to the linear array.

Lenses for high-resolution line scan:

  • Designed for high-resolution 12k line scan applications
  • Able to accomodate higher-resolution next generation line scan arrays
  • Large image circle up to 90 mm for long linear array sizes
  • High optical resolution for small pixel sizes down to 5 µm
  • Low distortion for excellent imaging accuracy
  • Optimized for magnification ratios from 0.33X to 2.0X
