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
