Protective Lens

Protective Lens

The protective mirror is an important consumable component in the optical system of the handheld laser welding machine. It is installed at the very front of the welding head and is mainly used to block the metal splashes, welding smoke, and oxidation particles generated during the welding process, preventing contaminants from entering the optical system and protecting the core optical components such as the focusing mirror and the collimating mirror.
During the laser welding process, a large amount of high-temperature splashes directly impact the front end of the welding head. The protective mirror acts as the first line of defense, effectively reducing the risk of damage to the internal lenses and ensuring the stable transmission of laser energy, thereby improving the welding quality and the stability of equipment operation.
It is suitable for laser welding processing of stainless steel, carbon steel, galvanized sheet, aluminum alloy, etc., and is widely used in industries such as sheet metal manufacturing, electrical cabinet production, door and window processing, kitchen equipment, metal furniture, advertising signs, elevator decoration, and mechanical equipment manufacturing.
Compared with ordinary optical lenses, high-quality protective mirrors have higher laser transmission rates, better high-temperature resistance, and longer service life, which can effectively reduce equipment maintenance costs and improve production efficiency.

Suggested replacement criteria:

• The lens surface turns yellow
• The lens has black spots
• The lens is burned
•  The lens cracks
• The coating is damaged
• The welding effect significantly decreases
