2000W Laser Welding Protective Lens

Laser protective lenses, also known as laser window panes or optical window panes, are engineered specifically for laser devices. They serve to protect human eyes and critical equipment components from laser radiation, high-temperature splashes, and dust. These lenses are widely used in laser processing equipment such as cutting, welding, marking, and engraving machines, as well as in laser medicine and experiments.

Key factors influencing their performance include transmittance, surface accuracy, thickness, parallelism, and substrate material. High transmittance enhances laser transmission and processing efficiency, while surface accuracy impacts imaging quality and laser focusing. Thickness ensures lens strength and stability without causing excessive laser loss or increasing costs. Parallelism maintains a stable laser direction during transmission, improving processing accuracy.

The choice of substrate material, such as glass, quartz, or crystals, depends on specific application requirements and determines the lens's physical and chemical stability. In summary, laser protective lenses are crucial for safeguarding eyes and equipment, with performance indicators and substrate material playing a vital role in their effectiveness.
