How to determine focal length: The Focal Length is the distance between the lens and the cutting material. The cutting requirements for different materials vary in terms of focal length. Typically, thinner materials require longer focal lengths, while thicker materials require shorter focal lengths. This is because the position of the focal point affects the focusing depth and diameter of the laser beam.

FIBER PATH: In the CO2 cutting process, the common optical path structure typically includes one focusing lens and two reflecting mirrors. The focusing lens is located after the output coupling mirror and is primarily used to adjust the direction and shape of the laser, making it as symmetrical as possible, and guiding the laser beam to the subsequent reflecting mirrors.

Important Consideration: Cleaning Instructions. 1. Use appropriate cleaning materials: Use gentle cleaning materials such as lens cleaning solution or lens cleaning tissues specifically designed for optical surfaces. 2. Clean in a dust-free environment: Ensure that the cleaning process is carried out in a clean and dust-free environment to prevent particles from getting onto the lens surface during cleaning. 3. Avoid excessive force, as excessive force can cause damage to the lens or misalignment of its optical properties.

Cloudray Test Process: Ensuring lens quality: CO2 lenses undergo high energy and high temperature in laser cutting processes, so their quality and durability are crucial. Testing can ensure that the lens materials, manufacturing, and coatings meet the quality requirements.

Determining optical performance: The optical performance of CO2 lenses is highly important for cutting and laser transport efficiency and quality. Testing can be used to evaluate optical performance parameters such as transmittance, reflectance, and scatter to ensure the proper functioning of the lens.

Detecting surface conditions: Testing can be used to detect scratches, dirt, or other defects on the lens surface.

In summary, CO2 lens testing can ensure that the lens quality, optical performance, and surface conditions meet the requirements, thus guaranteeing cutting quality and equipment reliability.
