The lens is moldy, what should I do, can I still use the mold inside the lens

If the mold grows outside the lens, you can use lens paper to dip the lens cleaning solution to clean it, or wipe it clean with an air blow and lens pen, and do not clean the lens with a napkin. Because the napkin has wood pulp inside, it can damage the fragile coating on the lens.

If it is more serious, you can also use lens polish paper dipped in 3% hydrogen peroxide to clean, and gently carry it on the surface of the lens, as long as the hydrogen peroxide is stained on the lens. Then gently wipe with mirror paper. Most of the lens mold is because the moisture-proof is not in place, and when the lens is not in use, you can buy a special moisture-proof box.

If you don't have a lot of lenses, you can make your own moisture-proof box. Buy a larger sealed crisper box, and then buy some color-changing silica gel desiccant, when the silica gel discoloration is observed, it means that the air humidity inside the crisper box has become larger, at this time, as long as the new silica gel desiccant can be replaced, and the used desiccant can be heated in the microwave oven, or you can continue to use.

It is best to send it to a professional lens cleaning store for maintenance or directly find the after-sales service of the camera, otherwise it is easy to get the lens or scratch it off.

1. Generally, the mold inside the lens needs to be sent to the maintenance station for inspection and maintenance, and the communication will often not be able to continue to be used;

2. Once the lens is moldy, it needs to be dealt with quickly to prevent more and more mold, if the mold grows outside the lens slippery opening, you can use the lens paper to dip the lens cleaning solution to clean, or wipe it clean with an air blow and lens pen, do not clean the lens with a napkin. Because the napkin has wood pulp inside, it can damage the fragile coating on the lens.

3. If it is more serious, you can also use the lens polish paper dipped in hydrogen peroxide with a concentration of 3% to clean it, and gently bring it on the surface of the lens, as long as the hydrogen peroxide is stained on the lens. Then gently wipe with mirror paper.

4. The long mold of the lens is because the moisture-proof is not in place, and when the lens is not in use, you can buy a special moisture-proof box;

5. If there are not many lenses, you can make a moisture-proof box. Buy a larger sealed crisper box, and then buy some color-changing silica gel desiccant, when the silica gel discoloration is observed, it means that the air humidity inside the crisper box has become larger, at this time, as long as the new silica gel desiccant can be replaced, and the used desiccant can be heated in the microwave oven, or you can continue to use.

If it is the inside of the lens: it can only be sent to a professional repair shop for cleaning.

If it is external: use a lens paper dipped in 3% hydrogen peroxide, more points, and gently carry it on the surface of the lens, as long as the hydrogen peroxide is stained on the lens. If the lens is too moldy, simply soak it in hydrogen peroxide.

After a short period of time (30 seconds is enough), gently wipe with lens paper dipped in anhydrous alcohol, the purpose of which is to use anhydrous alcohol to absorb the water on the lens and wash off the fat-soluble dirt on the lens. It should be that the part that has already grown mold is easy to grow in the future, so it is necessary to pay more attention to prevention in the future.

You can disassemble the lens yourself for cleaning, or you can send it to a professional repair shop.

1. Disassemble the lens by yourself and clean up the moldy lens, you can first use a clean soft brush to gently sweep away the moldy macrobacteria on its surface, and then spray it on its surface with an appropriate amount of diluted antifungal antibacterial agent, wait for it to dry, and spray it once with alcohol, but it is more difficult to disassemble the lens, and you need to ensure that the environment is dust-free, otherwise it will enter the dust and affect future imaging.

2. Send it to a professional repair shop, and check the nearby maintenance points on the official website of the lens brand. Professional lenses are cleaned of mold, usually by replacing a single lens, or waiting for an order.

1. When disassembling and installing spring blindness, follow the steps, disassemble the lens after it is in place, and the disassembly process should not be in a windy and dusty environment. During the disassembly process, you can observe whether there is dust on the lower sensor and the rear of the lens.

2. If the lens is used in a windy and sandy environment, it should be equipped with a UI lens to protect the lens. The UI mirror can generally be placed on the lens, and can be removed if there are special requirements for light.

3. After using the lens, you can check whether there is dust at both ends of the lens, and carefully clean it with a blown balloon and cover the lens cover. The lens is generally protected from mold, so it should be stored in a dry environment to prevent moisture, and the high-end lens cabinet will generally be equipped.

Introduction: With the development of science and technology, modern society, imaging, laser, infrared and other technical equipment have been widely used, these devices need to use optical glass to achieve their functions, but once the camera is stored in the wrong position, it provides space for the growth of mold. So what to do if the camera lens is moldy?

Let's take a look.

Causes of mold in camera lenses

In order to improve the performance of modern optical lenses, the surface of the lens is coated with multiple layers of polymer materials. This layer of synthetic material provides rich nutrients for the growth and reproduction of mold, which grows and multiplies on the surface of the optical lens by decomposing the components of the film, and the mycelium spreads on the surface of the lens in the form of dendrites, which makes the light transmission and imaging performance of the lens deteriorate, until the mycelium covers the entire lens.

Mold can also use the inorganic salts in the vitreous body of the lens to provide nutrients, so the mycelium also erodes longitudinally into the vitreous and penetrates. Optical lenses are generally composed of multiple lenses, and mold mycelium not only grows on the surface of the lens, but also spreads to the back of the lens through the edge of the lens, making it impossible to remove mold on both sides of the lens. In addition, mold spreads and ejects spores between multiple lenses, making the lens useless and irretrievable, resulting in scrapping.

What to do if the camera lens gets moldy

Mold grows on the surface of the lens in the early stages and is not easily visible to the naked eye. When it can be seen with the naked eye, it has generally caused some damage. If it is found very timely, the surface of the lens can be cleaned with a special solution, and later, the mycelium has been cut into the glass of the lens, and even if it is cleaned, the damage caused by the cut can no longer be remedied.

For lenses that have invaded the back of the lens, it is possible to disassemble the lens for cleaning, but it has already been caused'The loss is still irreparable, and the optical lenses have been finely adjusted after leaving the factory. In general, due to the lack of technical conditions, the performance of the lens after disassembly and reassembly will be affected. In addition, cleaning lenses is expensive, sometimes up to 30% of the purchase cost of the lens itself, for example.

In addition, if the cleaning is not thorough, it is not easy to change the sedan chair at that time to find the nuclear shop, and it will be ** in the future.

Precautions for storing camera lenses

Do not store the camera in a wooden cabinet, as wood tends to absorb moisture during the rainy season, and it is easy to cause mildew in the camera lens after a long time. The camera should not be stored in an iron cabinet, although the iron cabinet itself will not absorb moisture, but in such a closed environment it is difficult to dissipate moisture, once the camera is wet, the lens will become moldy.

Do not use leather cases, suitcases and towels to store the camera, leather and cotton cloth are very easy to absorb moisture, and it is better to slowly release moisture in a dry environment. Don't store the camera in the bag for too long, usually the bag is full of sponges, the sponge is very easy to absorb moisture, in addition, the bag is usually made of synthetic materials, it can prevent the humid air from the outside environment from entering the bag, but it also prevents the moisture inside the bag from escaping.

1. The surface of the lens is coated with a film composed of polymer materials, this layer of synthetic materials provides rich nutrition for the growth and reproduction of mold, and the mold decomposes the components of the film on the surface of the optical lens for growth and reproduction, and the mycelium spreads on the surface of the lens in the form of dendrites, so that the light transmission and imaging performance of the lens deteriorate, until the mycelium covers the entire lens.

2. Mold is the common name of filamentous fungi, which means "moldy fungi", which can often form branched and luxuriant mycelium, but do not produce large fruiting bodies like mushrooms. In moist and warm places, some grow on many items. Fluffy, flocculent or cobweb-resistant colonies that are visible to the naked eye are molds.

The main component of its cell wall is chitin.
