Introduction
The SK line scan camera series is designed for a wide
range of vision and inspection applications in industrial
and scientific environments. The SK22368U3TOC-LA is
highly portable and the robustly attached dedicated
connections enable external synchronization of the
camera and the output of data to the USB 3.0 port of the
computer.
The USB 3.0 connection supplies power to the camera
and the camera is hot-pluggable, providing the greatest
degree of flexibility and mobility. The computer does not
require a grabber board, allowing a laptop to be used
when space or weight restrictions are also at a premium.
Once the camera driver and the SkLineScan®program
have been loaded from the SK91USB3-WIN CD then the
camera can be parameterized. The parameters, such as
integration time, synchronization mode or shading
correction, are permanently stored in the camera even
after a power-down or disconnection from the PC.
The oscilloscope display in the SkLineScan®program
can be used to adjust the focus and aperture settings, for
evaluating field-flattening of the lens and for orientation
of the illumination and the sensor, see Software:
SkLineScan, p. 9.

Installation and Setup
2 Installation and Setup
2.1 Mechanical Installation: Mounting Options and Dimensions
Casing type AT3L
Mounting Options
• The best fixing point of the camera is the collar for
the mounting bracket SK5105-L (available as an
accessory).
• Four threaded holes M3x6.5 mm provide further
options for customized brackets.
• The length and weight of the optics might be beyond
the capability of the standard mounting bracket
SK5105-L. For this purpose, a second mounting
bracket type SK5105-2L to hold the tube extension
ring(s) is more appropriate.
Optics Handling
• If the camera and the optics are ordered as a kit,
the components are pre-assembled and shipped
as one unit. Keep the protective cap on the lens
until the mechanical installation is finished.
• If you must expose the sensor or lens surface,
ensure the environment is as dust-free as possible.
• Gently blow off loose particles using clean
compressed air.
• The sensor and lens surfaces can be cleaned with
a soft tissue moistened with water or a water-based
glass cleaner.

Camera Control and Performing a Scan
Signal Window / Oscilloscope Display
The signal window plots the digitalized brightness profile as signal intensity (y-axis) versus the sensor length (x-axis)
at a high refresh rate. The scaling of the y-axis depends on the resolution of the A/D converter: The scale range is
from 0 to 255 for 8-bits and from 0 to 4095 for 12-bits. The scaling of the x-axis corresponds with the number of
pixels in the line sensor.
Basic Visualization of the Sensor Output
Zoom Function
For high numbers of sensor pixels, the limited number of display pixels might be out of range, in which case the
zoom function can be used to visualize the brightness profile in detail. Magnification of one or several sections of
the signal allows individual pixels to be resolved for a detailed evaluation of the line scan signal.
Window Split Function
The signal window can be split horizontally into two sections. Use the split handle Bat the top of the vertical scroll
bar and afterwards arrange the frames using the zoom buttons in the toolbar.
