Do you really know what to pay attention to before cleaning optical lenses?
In recent years, China has gradually become an important production base for optical glass and optical lenses in the world. The main materials of optical lenses are colorless optical glass, colored optical glass, infrared optical material, crystal material, glass material and plastic material. They have high transparency, high uniformity of physical and chemical properties and specificity. Accurate optical constants.
The main raw material of the optical lens is optical glass, which has a higher refractive index than the resin lens, so that the optical lens is thinner than the resin lens in the same degree. The optical lens has good light transmittance and mechanochemical properties, and has a constant refractive index and stable physical and chemical properties. The optical lens has superior properties, is not easy to draw, and has a high refractive index. The higher the refractive index, the thinner the lens. However, the glass piece is fragile and the material is heavy. When selecting the frame, you should try to choose a smaller frame to ensure the wearing comfort.
During the inspection and installation of optical lenses, care must be taken to protect the lenses from damage and contamination. At the same time, after a new lens is installed, it should be cleaned regularly. This process is quite simple. Proper operation will extend the life of the lens and reduce costs. On the contrary, it will reduce the service life. If the lens is contaminated but not damaged, the operator can disassemble and clean it. Of course, some method that avoids damage to the lens and further contamination should be used.
So, what are the precautions for optical lenses before cleaning? Let's take a look at it together:
1. Always wear finger cots or rubber gloves when taking the lens, because the dirt and oil droplets on the hands will stain the lens, causing performance degradation.
2. Do not use any tools to take the lens, such as tweezers.
3. The lens should be placed on the lens paper to avoid damage.
4. Do not place the lens on a rough or hard surface. The infrared lens is easily scratched.
5. Do not clean or touch the surface of pure gold or pure copper.
