c. Do not place the lens in a dark, humid place, which will cause the lens surface to age.
d. the lens surface stained with dust, dirt, or water vapor, easy to absorb the laser caused by damage to the lens coating; ranging from the impact of laser beam quality, while no laser beam.
e. When the lens is damaged, please contact the Han family laser service department to repair, try not to use the lens has been damaged, otherwise it will accelerate the damage to the repair of the lens.
f. Do not use too much pressure when installing or replacing a mirror or focusing lens, otherwise it will cause deformation of the lens, which will affect the quality of the beam.
4.the installation or replacement of optical lenses
a. Before installing the optical lens to pay attention: wear clean, with soap or detergent to clean hands and wear white clean gloves; is strictly prohibited any part of the hand contact lenses; take the lens, should wear gloves, and from The side of the lens to take, do not directly touch the lens coating surface.
b. When assembling the lens, do not use the mouth to blow the lens toward the lens; the lens should be placed on the clean desktop, the next pad a few lens paper. Take the lens should be careful to prevent bruises and falls, and in the lens coating surface, are not allowed to exert any force; installation of the lens mirror mirror should be clean, with a clean air gun to clean the mirror in the dust and dirt , Then, remove the lens, gently into the mirror seat. c. When installing the lens to the mirror holder, do not use the lens to use the power to prevent the lens from being deformed, thus affecting the quality of the beam.
d. Precautions when replacing the lens: Do not take any pressure on the lens until the wrapping paper has not been opened before removing the lens from the box; remove the mirror and focus from the box When you remove the lens, remove the dust from the mirror and remove the dust from the mirror. After removing the lens, remove the lens from the lens. Remove the lens from the lens. The lens on the optical lens special paper; remove the lens holder and the shelves of dust and dirt, should not be assembled when the other foreign body fell on the lens; installation of the lens in the mirror seat, do not excessive force, so as not to lens deformation; After the assembly is complete, clean the dust and foreign matter on the lens with a clean air gun.
5.clean the lens steps
Different lenses, the clean method is different. When the mirror is flat and no mirror seat, use the lens paper cleaning, such as cleaning the mirror; when the mirror is a curved surface or mirror with a mirror, you should use a cotton swab clean, such as cleaning the focusing lens.
a. Use the lens paper to clean the lens steps: blow out the dust on the surface of the lens with a blower; clean the lens surface with alcohol or lens paper, do not drag the lens with a dry lens directly on the mirror, The surface of the lens, drop 2 to 3 drops of high purity alcohol or high purity acetone, the direction of the operator will be slowly out of the lens paper, repeated the operation of the operation several times until the mirror so far; if the mirror is very dirty, You can fold the lens paper 2 to 3 times, repeat the above steps until the mirror clean so far.
b. Use the cotton swab to clean the lens steps: first use the gun to blow off the dust on the mirror; then clean the stain with a clean cotton swab; with a new high-purity alcohol or acetone cotton swab from the center of the lens along the circular motion, After each week, for another clean cotton swab, repeat the above operation, until the lens clean so far, do not use the already used cotton swab to operate; with a clean cloth to clean the lens, remove the residual marks on the mirror, Scratched the mirror; will clean the lens to get plenty of light to observe the place, if the lens reflection is good, that the lens has been clean, if the lens reflection is not good, you have to continue to clean the lens; will have a clean lens , According to the method described above, the lens placed in the mirror seat.
