What Are The Features Of Line Scan Lenses? How Are They Different From Ordinary Lenses?

A line scan lens is a lens specifically used to continuously photograph the surface of an object being measured from one direction. It is usually used in conjunction with a linear array sensor to continuously scan the object being measured by continuous movement or translation to obtain an image of the entire object.

1、What are the features of line scan lenses?

The main feature of a line scan lens is its ability to capture images of high-speed moving objects. Let’s take a look at its specific features:

High-speed imaging

Line scan lenses are suitable for high-speed imaging applications and can quickly capture continuous target images. They are suitable for use in industrial inspection, automated production and other fields.

Single line scan

The design of the line scan lens is suitable for single-line scanning imaging technology, which can scan the target line by line and achieve high-speed imaging.

High resolution

Line scan lenses typically have high resolution, providing clear, detailed imaging and are suitable for demanding imaging applications.

Lens size

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

Lens Optimization

Line scan lenses are optimized for the special imaging requirements of line scan cameras and can achieve high-quality line scan imaging.

Specific applications

Line scan lenses are usually used in specific applications that require single-line scanning imaging, such as high-speed packaging inspection, printing quality inspection, wood sorting, etc.

2、What is the difference between a line scan lens and a normal lens?

Line scan lenses are usually used for specific high-speed imaging applications, while ordinary lenses are suitable for general shooting needs. The two are mainly different in the following aspects:

Different lens design

Line scan lenses usually adopt a long strip design to meet the special requirements of single-line scanning imaging; ordinary lenses usually adopt a circular or rectangular design.

Different imaging methods

Line scan lenses are suitable for line scan cameras and use single-line scanning to perform imaging; ordinary lenses are suitable for traditional cameras and use full-frame or area imaging.

Using single line scan imaging

Different resolution requirements

Line scan lenses usually have higher resolution and are used to capture images with rich details, suitable for demanding imaging applications; ordinary lenses have relatively lower resolution requirements.

Different long exposure capabilities

Line scan lenses usually have better long exposure capabilities and can achieve clear images under high-speed motion; ordinary lenses may have blur or jitter problems under long exposure.

Different application areas

Line scan lenses are usually used in specific applications that require single-line scanning imaging, such as high-speed packaging inspection, printing quality inspection, etc.; ordinary lenses are suitable for a variety of general shooting needs, such as portraits, landscapes, still lifes, etc.
