Product Description
Contact Image Wide Field Linear Scanning camera
Contact Image Sensor(CIS）is a scanning camera that closely arranges the photosensitive
units and directly collects the light information reflected by the scanned object, because it
does not require a lens group, so it is more compact and less expensive.
CIS is composed of Light source、Rod Lens array、CMOS image sensor array and its
Printed Circuit Board、Protective glass、Housing and so on
The CIS line scan camera uses a CMOS color sensor with an integrated LED light source
and lens to support color image and grayscale image acquisition. The image produced by the
contact image sensor is a target 1:1 reproduction, without distortion and without additional
correction, resulting in excellent color realism and perfect resolution. At the same time, the
light source system of CIS cameras is highly flexible, and the internal light source type can be
customized for the target detection object, and it can also be combined with the external
light source system to adapt to a variety of detection types.
2.The difference between CIS line scan camera and traditional line scan camera
① Parameter advantage：
Width: Above 91.5mm-2300mm
Accuracy: High: 10μm（2400DPI）
Speed: High:150K
② Imaging effect：Due to the distortion of traditional line scan cameras, CIS industrial line
scan cameras have no distortion, so with the gradual increase of effective scanning width, the
advantages of imaging effect of CIS industrial line scan cameras become more and more obvious
③ Structural advantages：CIS camera sensor, light source and lens integrated design, more
compact structure, more convenient installation.

4.Industry applications
CIS line scan cameras are mainly used in continuous material surface defect detection,
such as PCB detection, lithium battery film inspection, printing and packaging inspection, photovoltaic panel inspection, metal plate inspection, glass inspection, fabric textile inspection,
honeycomb ceramic inspection, scanner/copier, etc. The object to be measured passes
through the camera at a constant speed, and the camera continuously scans its surface to
detect surface defects. (As shown in the figure below, the red arrow indicates the direction of
movement of the object relative to the camera)
① PCB: missing components, open circuit short circuit, line width line diameter, characters,
surface defects, aperture size, aperture position, etc
② Lithium battery film: whether there are holes, scratches, stolen goods, abnormal overlap,
unevenness, width measurement, etc. on the surface
③ Printing and packaging: color, characters, whether missing printing, numbers, two
dimensional codes, barcodes, etc
④ Cloth textile leather: stripes, scratches, etc
⑤ Glass: fingerprints, cracks, chipping, etc
⑥ Metal: rust; Burn points; Scratches on the back; fingerprint printing; parietal convexity;
crease strip material; ink contamination, etc
⑦ Honeycomb ceramics: number of plugging holes, plugging rate, mesh number, etc
