Precautions when using optical lenses

1. Wear finger cots when using optical lenses. If there are substances such as acid and salt that are easy to corrode the glass surface on your hands, do not touch the optical lenses directly, which will cause imprints on the optical lenses. May become permanent speckle, affecting the image quality of optical components.

2. When using optical lenses, handle them with care. Many optical lenses are made of glass, which can easily cause bumps, chipping, and scratches.

3. When moving the optical lens, hold the edge of the lens, do not directly touch the light-transmitting surface, even if you wear finger cots.

4. When the optical lens is not used, it should be placed on a soft surface. Do not directly place the bare lens on glass, metal, desktop or unclean paper, which will easily cause the lens to be scratched.

5. When there is dust on the lens surface, use a clean ear-washing ball to blow the dust off.

6. When the lens is stained or sweaty, use lens tissue or silk cloth dipped in alcohol or acetone to gently wipe.

7. When storing the lenses, use clean capacitive paper or lens tissue to pack the lenses, and store them in an environment with a moderate temperature of about 23°C and humidity below 40%. If conditions permit, they can be stored in a dry cabinet.

8. When storing lenses, do not stack optical lenses together, and do not overlap each lens.

9. When the lens is dirty, it should be cleaned immediately, but pay attention to prevent the lens from being scratched. Dust can easily cause the lens to be scratched.
