Characteristics of Line Scan Lens

Line scanning lens is a specialized lens for line scanning cameras, mainly used for image capture and processing of continuous moving objects.

1, High Resolution: line scanning lens can provide high-resolution images, which is particularly important for applications that require fine detection.

2, Narrow field of view: the field of view of the line scanning lens is usually narrower, which allows it to cover a larger range in the horizontal direction, suitable for detecting objects with a large width.

3, Low Aberration: In order to ensure image quality, the line scanning lens is designed to reduce aberrations, to ensure the authenticity and accuracy of the image.

4, Fast Focus: line scanning lens has the ability to quickly focus to adapt to different distances and speeds of the object detection needs.

5, High-speed scanning frequency and fast exposure time: line scanning lens can be in high-speed movement of the object image capture, with high-speed scanning frequency and fast exposure time, to ensure the stability and clarity of the image.

Characteristics of Face Lens

1, fixed field of view angle: the size of the field of view of the surface array lens is directly limited by the size of its pixel array, usually has a fixed field of view angle.

2, high resolution: surface array cameras usually have more pixels, so the surface array lens can provide higher resolution and capture more details.

3, high sensitivity: surface array cameras usually have higher sensitivity, which can obtain better image quality under lower light conditions.

4, for static or slow-moving applications: because the surface array camera can capture the entire image at once, so it is more suitable for static or slow-moving application scenarios.

Differences between line-scan and surface-matrix lenses

Application Fields:

Line scan lens: widely used in industrial automation, print inspection, wood inspection, food sorting and other fields, especially suitable for applications that require high-speed continuous imaging and analysis of objects in motion. For example, in lithium battery production assembly, quality inspection and print inspection, the line scanning lens can scan the circuit board and other objects at high speed, and collect images with sharpened edges and clear contours, so as to accurately and quickly identify defects.

Face array lenses: are more often used in machine vision, remote sensing, medical imaging and security monitoring and other fields, which require high image quality and detail, but the object's movement speed is relatively slow.

Imaging effect:

Line Scan Lens: The imaging effect is characterized by high speed and high precision, capable of capturing images of high-speed moving objects in real time and performing high-precision image analysis.

Face array lens: is known for its high resolution and high sensitivity, able to capture rich image details, suitable for static or slow-moving application scenarios with high requirements for image quality.
