Characteristics of Line Scan Lens and Differences with Ordinary Lens

Line scan lens is specialized lenses used for continuously capturing the surface of the object being inspected from one direction. They are typically used in conjunction with line array sensors, continuously scanning the object being inspected through constant movement in order to obtain the image of the entire object.

What Are the Characteristics of Line Scan Lens?

The main characteristic of line scan lens is their ability to capture images of fast-moving objects. Here are the specific characteristics:

High-speed imaging

Line scan lens is suitable for high-speed imaging applications, capable of rapidly capturing continuous target images, which makes them ideal for industrial inspection, automated production, etc.

Single-line scanning

Line scan lens is designed for single-line scanning imaging technology, capable of scanning targets line by line to achieve high-speed imaging.

High resolution

Line scan lens typically has high resolution, providing clear and detailed imaging effects, suitable for high-demand imaging applications.

Lens size

Line scan lens is usually designed in a strip shape to meet the special requirements of single-line scanning imaging, which is different from the shape of traditional camera lenses.

Lens optimization

Line scan lens is optimized for the specific imaging needs of line scan cameras, achieving high-quality line scan imaging.

Specific applications

Line scan lens is typically used in specific applications that require single-line scanning imaging, such as high-speed packaging inspection, print quality inspection, wood sorting, etc.

What Are the Differences Between Line Scan Lens and Ordinary Lens?

Line scan lens is typically used for specific high-speed imaging applications, while ordinary lens is suitable for general photographic needs. The main differences are as follows:

Different lens designs

Line scan lens usually adopts a strip-shaped design to meet the special requirements of single-line scanning imaging; ordinary lens typically has a round or rectangular design.

Different imaging methods

Line scan lens is suitable for line scan cameras and use single-line scanning for imaging; ordinary lens is suitable for traditional cameras, using full-frame or area imaging methods.

Different resolution requirements

Line scan lens typically has higher resolution to capture detailed-rich images, suitable for high-demand imaging applications; ordinary lens has lower resolution needs.

Different long exposure capabilities

Line scan lens usually has better long exposure capabilities, able to achieve clear images under high-speed movement; ordinary lens may experiences blur or shake issues under long exposure.

Different application fields

Line scan lens is typically used in specific applications requiring single-line scanning imaging, such as high-speed packaging inspection, print quality inspection, etc.; ordinary lens is suitable for various general photographic needs, such as portraits, landscapes, still life, etc.
