The Working Principle And Purpose of Laser Scanning Lens

A laser scanning lens is an optical lens that uses a laser beam to scan. It is usually used in laser equipment such as laser scanning microscopes, laser printers, and laser cutting machines.

1.Working principle of laser scanning lens

The working principle of the laser scanning lens deeply integrates optical principles and precise control systems, which work together to achieve high-precision focusing and scanning of the laser beam on the target, and realize high-speed, high-resolution scanning and processing capabilities.

Laser scanning lenses use a combination of laser beams and scanning lenses to achieve accurate three-dimensional measurement and scanning. The following is a detailed explanation of the working principle of laser scanning lenses:

(1)Control system

The precise operation of the laser scanning lens is inseparable from an efficient control system. The system integrates components such as drives, encoders, and advanced control software to accurately control reflective elements (such as scanning mirrors) through precise algorithms.

This control mechanism ensures that the laser beam can move stably and accurately along the preset path, achieving high repeatability and accuracy during the scanning process.

(2)Optical focus

The laser scanning lens has a built-in focusing lens assembly, whose key function is to accurately focus the laser beam on the sample surface. By adjusting the distance between the lens and the laser source and the shape of the lens, the system can finely control the position and size of the focus point to ensure that the laser energy is concentrated on the target area, improving the efficiency and quality of scanning or processing.

(3)Scan control

The laser scanning lens uses advanced scanning control technology. This technology enables the laser beam to flexibly scan the sample surface horizontally and vertically by precisely adjusting the angle and rotation speed of the scanning mirror.

The fast response and precise positioning capabilities of the scanning mirror ensure that the laser beam can move smoothly along the preset complex trajectory, achieving a comprehensive and detailed scan of the sample surface.

(4)Zoom in and focus

During the scanning process, the laser scanning lens also has the function of magnification and focus optimization. In other words, the system can dynamically adjust the focus depth and scanning range of the laser beam according to actual needs, so as to achieve accurate processing of tiny areas. This function greatly improves the accuracy and resolution of scanning processing.

2.The main purpose of laser scanning lens

Laser скануючі об'єктиви are widely used in industrial production and scientific research, especially in precision manufacturing, quality inspection and other fields. Let’s take a look at the main uses of laser scanning lenses:

(1)Laser imaging

The laser scanning lens has significant advantages in the field of laser imaging. It accurately scans the laser beam on the surface of the target object and non-contactly captures and reconstructs its three-dimensional morphology and structural information.

This technology is widely used in the fields of three-dimensional scanning, medical image analysis, geological exploration and archaeological research, providing strong support for the digitization and visualization of complex shapes.

(2)Laser marking

In the field of laser marking, laser scanning lenses have become an ideal tool for marking, engraving or patterning workpiece surfaces due to their high precision, high speed and non-contact characteristics. This method can achieve non-contact, high-precision and high-speed marking effects, and is suitable for marking needs of various materials.

(3)Laser engraving

The laser scanning lens can perform laser engraving. By finely controlling the focal length and power of the laser beam, it can create detailed and richly patterned engravings on the surfaces of wood, glass, leather and other materials. Laser engraving is suitable for materials of various hardnesses, such as wood, glass, leather, etc.

(4)Laser cutting

In the field of laser cutting, laser скануючі об'єктиви have achieved efficient and accurate cutting of workpiece materials. Utilizing high-energy-density laser beams, combined with precise scanning control, the laser scanning lens can achieve rapid cutting of complex shapes on a variety of materials such as metal, plastic, and paper.

It has the characteristics of high efficiency, high precision, and low loss, and is widely used in the processing of metal, plastic, paper, and other materials.
