Selecting the right protective lens for a laser cutting machine is crucial. Protective lenses, as consumable components, primarily protect the focusing lens from dust and slag. Besides being widely used in laser cutting machines, they are also essential components for other laser equipment, such as laser marking, laser welding, and laser engraving. Therefore, protective lenses have broad market applications. The price of protective lenses on the market varies greatly, ranging from tens to hundreds of yuan. Their quality also varies greatly, and defective products are common. Improper selection can lead to increased laser loss, frequent damage to the protective lens, and unstable product quality, resulting in significant losses for the company. Therefore, selecting the right protective lens is a crucial task.

Selecting a protective lens for a laser cutting machine involves three key steps:

01. Dimensions: The dimensions must match, which is straightforward.

02. Material: Considering laser power and cost, materials such as K9 and quartz can be selected. In practice, professional manufacturers classify these materials into multiple grades, allowing customers to select the appropriate specifications based on their specific needs.

02 Coating Technology: Different laser anti-reflection coating technology parameters are used depending on the operating environment.

Although the protective lens of a laser cutting machine is a consumable part, regular cleaning can extend its lifespan and reduce production costs. The following are three cleaning steps summarized by Eagle Laser:

1. During disassembly and installation, be careful to avoid excessive force and collision with hard objects. The protective lens has an anti-reflection coating on its surface and must be protected from contamination, moisture, grease, and scratches.

2. The protective lens of a laser cutting machine should generally be inspected before use and before and after cleaning. Because most contaminants and surface defects are small, magnifying equipment is often required for inspection.

3. When cleaning the protective lens of a laser cutting machine, clean wipes and optical-grade solvents are typically used to prevent damage from other contaminants.
