What are the cleaning and maintenance methods for lens glass?
Release Time : 2025-02-24
Cleaning and maintaining the lens glass is a key step to ensure the image quality of photographic or video equipment.
First, for dust and particles on the surface of the lens glass, avoid using paper towels or clothing to wipe directly, as this may scratch the lens surface. The correct method is to use an air blower or a soft brush to gently blow or sweep away large particles of dust on the lens. The air blower can blow dust away from the lens surface through high-pressure airflow, while the soft brush can be used to clean fine particles that are difficult to blow away.
Secondly, if there are stains such as fingerprints and oil stains on the lens glass, you can use lens cleaning fluid and lens paper or a dedicated lens cleaning cloth to clean it. When using cleaning fluid, you should first drop a small amount of cleaning fluid on the lens paper, and then wipe the lens surface in a spiral from the inside to the outside to avoid scratches caused by wiping back and forth. Be gentle when wiping to avoid damaging the lens coating.
In addition, for stubborn stains or fingerprints that are difficult to remove, you can use the carbon powder head of the lens pen to gently absorb the stains. The lens pen usually has a sticky carbon powder head that can absorb and remove stains on the lens surface without damaging the lens coating. After using the lens pen, use a soft brush or air blower to clean the excess carbon powder.
In terms of maintenance, the lens glass should avoid being exposed to humidity, high temperature or strong magnetic field for a long time. A humid environment may cause the lens to mold, a high temperature environment may cause the lens to deform, and a strong magnetic field may interfere with the normal operation of the lens. In addition, you should avoid using detergents containing abrasive particles or rough cleaning tools to avoid scratching the lens surface.
Finally, when the lens is not in use, the lens cap should be covered to prevent dust from entering. At the same time, regular inspection and cleaning of the lens cap is also an important part of keeping the lens clean.
Correct cleaning and maintenance methods can effectively extend the service life of the lens glass and maintain its good imaging quality.
