from the lens, avoid dust and other objects on the lens; after taking out the lens, use a spray gun to
remove the dust on the lens, and then Put the lens on the special paper for the optical lens; remove
the dust and dirt on the lens support frame and fixing frame, and avoid other foreign objects
falling on the lens during assembly; when installing the lens on the lens holder, do not use
excessive force to avoid lens distortion; After the assembly is complete, use a clean air spray gun
to remove dust and foreign objects on the lens again.
c. Steps to clean the lens
Different lenses have different cleaning methods. When the mirror surface is flat and there is no
lens holder, use lens paper to clean, such as cleaning the mirror; when the mirror surface is curved
or the mirror surface has a lens holder, use a cotton swab to clean, such as cleaning the focusing
lens.
1) Steps to clean the lens with lens paper: Use a blower to blow off the dust on the surface of the
lens; clean the surface of the lens with alcohol or lens paper. Do not use dry lens paper to drag
directly on the lens surface, but place the lens paper flat Put 2 to 3 drops of high-purity alcohol or
high-purity acetone on the surface of the lens, and slowly pull out the lens paper horizontally
toward the operator. Repeat the above actions several times until the lens surface is clean; if the
lens surface is very dirty, Fold the lens paper in half 2 to 3 times and repeat the above steps until
the mirror surface is clean.
2) Steps to clean the lens with a cotton swab: first use a spray gun to blow off the dust on the
mirror surface; then use a clean cotton swab to remove the dirt; use a new cotton swab moistened
with high-purity alcohol or acetone to move in a circular motion from the center of the lens to
scrub the lens. After wiping for a week, change to another clean cotton swab and repeat the above
operation until the lens is clean. Never use cotton swabs that have been used for operation; clean
the lens with a clean cloth to remove the residual marks on the mirror surface, and be careful not
to Scratch the mirror surface; take the cleaned lens to a well-lit place for observation. If the
reflection of the lens is good, it indicates that the lens has been cleaned. If the reflection of the lens
is not good, continue to clean the lens; remove the cleaned lens , According to the method
described above, place the lens on the lens holder.
d. Storage of optical lenses

environment, otherwise the lens will be easily damaged by condensation and frost when taken out;
the storage environment temperature should not exceed 30℃, otherwise it will affect the coating
on the lens surface.
3) Keep the lens in the box. The lens should be placed in a non-vibrating environment, otherwise
it will easily cause the lens to deform and affect the performance of the lens.
4.4 Maintenance and maintenance during long-term
parking
Pay attention to the placement of the laser head when the handheld laser cleaning machine is
parked for a long time. If necessary, it is best to fix it in one place to avoid collision and smash the
lens in the laser head. Remember to seal the duckbill when the laser cleaning system is not used.
To prevent dust from entering.
