The fiber laser protective lens is located above the focusing lens; it serves to block dust, metal spatter, slag, and other contaminants, thereby protecting the internal optical components of the laser head.

Coating parameters play a decisive role in the optical lens manufacturing process, directly influencing the lens's optical performance, durability, and ultimate imaging quality.

After years of development in the laser industry, there has been a relatively complete solution to the above-mentioned focus errors. The laser focus can be adjusted by manually adjusting the mechanical device on the laser head. In addition, the current laser head with automatic focusing function is relatively mature, and combined with a professional numerical control system, it can help customers solve the problem of errors in laser cutting.

Replacing your laser machine consumables when they show wear and tear is extremely important. It will greatly reduce working hours lost and improve how efficiently your laser cutting machine can produce a quality product.
