Laser protective lens 20x3 1070–1090 nm

Description

This 20x3 laser protective lens is designed to operate within a 1070 to 1090 nm wavelength range, commonly used on fiber laser welding systems. Its role is simple yet critical: to act as a shield between spatter/particles and the head optics, preserving beam performance and welding consistency.

Manufactured from plasma-fused quartz, it provides optical transmission suited to industrial constraints while keeping a clean surface for longer when proper maintenance is performed. The result: better beam control, more consistent visual quality, and reduced risk to the laser head.

How to replace the F150 laser lens?

1. Loosen the locking screw on the protective lens holder housing.
2. Remove the lens protective holder.
3. Wrap the objective seat cavity with masking paper (dust protection).
4. Gently wipe the front of the objective with a cotton swab or a clean cloth soaked in alcohol.
5. Remove the protective mirror holder and clean the other side of the protective mirror.
6. Place the protective mirror into its holder, push it into position, then tighten the screws.

Replace the laser protective lens after 8 to 10 hours of welding to reduce the risk of damage to the laser head.

Who is it for?

For workshops and production lines looking to maintain a clean welding cycle, reduce unplanned downtime, and protect optics on MA1-35, MA1-45, and MA1-65 torches.
