How to prevent secondary pollution of optical lenses

  In the average power output of laser, all lenses metropolitan due to the reason of the manufacturing process or polluted by external factors such as the lens of the laser wavelength absorption in particular, over time to make the lens shortened lifespan, caused by damage to the lens effect use even stop.
  Because of the pollution that causes the lens to be highly absorbed, the thermal lens effect causes many problems.Lens substrate of irreversible thermal stress, produced during the beam through the lens of power loss, focused on the deviation of the position of light spot, premature failure of the coating layer can result in damage to the lens.We are doing is exposed to the air for the lens cleaning, to follow the lens cleaning requirements and matters needing attention, if any materials, the result will cause new pollution even scratch lenses, caused irreparable damage.
  It's important to keep your lenses clean.To maintain good cleaning habits, carefully clean your lenses and remove man-made causes such as fingerprints or saliva.Work out in the optical system, cleaning, dis-assembly, installation time all want to wear gloves or medical gloves, always follow the requirements and matters needing attention of cleaning lenses.In the process of cleaning, only the required materials, such as the lens paper of optical use, and the reagent grade ethanol, etc.The removal of any lens, removal and installation of shortcuts will result in the shortening of lens life and even permanent damage.After determining that a certain lens is contaminated, the lens should be blown by the ear ball until the surface is not as good as the particle.Be careful not to blow with your mouth, because the air that is blown out is mostly oily, and the water will further contaminate the lenses.
  If we can keep the lens clean, it will undoubtedly prolong the life of the machine.
