Line-scan lenses work differently than common face-matrix lenses. While a face-matrix lens acquires an image of the entire scene at once, a line-scanning lens images the scene by scanning it line by line. It captures only one line of image information at a time, and then through the relative motion between the object and the lens, these line-by-line acquisition of the line image is combined into a complete two-dimensional image.

A distinguishing feature of line-scan lenses is their extremely high resolution. Because of their focus on progressive scanning, they are able to achieve higher pixel densities on each line, thus capturing very fine details. This allows line-scan lenses to excel in scenarios that require high-precision imaging, such as large-format flatbed inspection, print quality inspection, and more.

Line scan lenses also have excellent scanning speed and efficiency. The ability to quickly acquire a large amount of image data, suitable for high-speed movement of the object detection, such as in the production line on the fast-moving product inspection and quality control.

Application Scenarios:

1、In the textile industry, it can be used to detect defects and texture of fabrics;

2、In PCB circuit board manufacturing, it can accurately detect the integrity of the line and small defects;

3、In the food packaging industry, the line scanning lens can be used to quickly and accurately detect the continuous movement of packaging materials to ensure product quality.

Line-scan lenses have a greater depth of field, which means that objects remain clearly imaged at different distances within a certain range, reducing the complexity and effort of focusing.

Line scan lens with its unique working principle, showing a high resolution, high scanning speed, large depth of field and other characteristics, in many industrial and scientific research in the field of imaging applications play an irreplaceable role in improving production efficiency, ensure product quality and promote scientific research to provide strong support. With the continuous progress of technology, line scan lenses are expected to show more powerful application potential in more fields.
