Problems of optical microscope optical glass cleaning
Optical glass is used for lenses, prisms, lenses, etc. of instruments. During manufacturing and use, it is easy to be stained with oil, water-wet dirt, fingerprints, etc., which will affect imaging and light transmittance. To clean optical glass, different cleaning agents, different cleaning tools, and different cleaning methods should be selected according to the characteristics and structure of the dirt. To clean lenses coated with anti-reflection coatings, such as cameras, slide projectors, and microscope lenses, use about 20% alcohol and about 80% ether to prepare cleaning agents for cleaning. When cleaning, apply a soft brush or cotton ball with a small amount of cleaning agent, and make a circular motion from the center of the lens outward. Do not soak this type of lens in cleaning agent, and do not wipe it hard when cleaning the lens, otherwise it will damage the anti-reflection coating and damage the lens.
The method of cleaning prisms and plane mirrors can be carried out according to the method of cleaning lenses.
The above cleaning agent can also be used to clean the greasy mist, water wet mist and oil-water mist on the optical glass. The cleaning method is similar to that of cleaning the lens.
Mold on the surface of optical glass is a common phenomenon. When the optical glass is moldy, the light will scatter on its surface, making the image blurred, and in severe cases, the instrument will be scrapped. The reason for mold on optical glass is mostly because of the microbial spores attached to the surface. When the temperature and humidity are suitable and the required "nutrients" are available, they will grow rapidly and form mold spots. It is especially important to prevent mildew and pollution on optical glass. Once mildew occurs, it should be cleaned immediately. Pay attention to drying.
