12K High Resolution Lenses
|
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).
Makro-Symmar lenses are designed for industrial machine vision applications and satisfy even
the most stringent requirements of 12k line scan applications. Four different versions 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.
