Laser safety goggles are designed to prevent or minimize laser harm to eyes. Laser beams are of high energy. Human eyes are
very sensitive to laser beams, especially the retina and other tissues. They can absorb laser beams of various wavelengths.
Therefore, the damage threshold of laser beams to eye tissues is much lower than other organs, and the macular region of
eyes is particularly sensitive.
With special optical design, laser safety goggles can reflect or absorb laser beams, preventing direct exposure of eyes to laser
beams, and thus preventing or minimizing laser harm to eyes.
Note that even with the safety goggles, you should not look directly into laser beams. Looking directly into laser beams may
cause irreversible and permanent eye damage.
Some laser machines are equipped with protective enclosures and interlocking devices to meet the standards of Class 1 laser
machines, which can be used without the use of safety goggles. For Class 4 laser machines, you need to wear laser safety
goggles and follow other safety instructions.
An air assist set draws in air and blows it into a laser machine through an air tube. The airflow can be adjusted. Generally, a
small airflow is used to clean the processing area and cool the processed material part during laser engraving, and a large
airflow is used in laser cutting not only for cleaning and cooling but also for smoke exhaustion and residue blowing.
For better processing results, you are advised to use an air assist set. You can go to https://www.xtool.com/ to purchase
one.
■ Cleaning the processing area
When a high-energy-density laser beam falls on a material, smoke, dust, and debris may be generated. The airflow generated
by the air assist set can disperse them to keep the processing area clean and thus improve the processing efficiency and
processing results.
■ Cooling the processed material part
When a high-energy-density laser beam falls on a material, the temperature of the processed material part rises rapidly. The
material may deform, melt, develop cracks, or get scorched. The airflow generated by the air assist set can blow away some of
the heat to prevent material damage and thus improve the processing stability, precision, and results.
■ Facilitating smoke exhaustion
Harmful smoke or fumes may be produced during laser cutting of certain materials. The large airflow generated by the air
assist set helps to exhaust them from the machine, keeping the workspace safe.
■ Blowing away residues
During laser cutting of thick or hard materials, the large airflow generated by the air assist set can blow away residues in the
cutting gap, making the cuts smoother and more precise.
