How to remove the traces of the lens glass
When wiping the lens glass, do not use a napkin because it is easy to leave tissue fibers on the lens. There are two types of materials that can be used to wipe the lens: one is fiber cloth, which is more durable and won't shed hair, but it doesn't absorb water very much, and the effect of wiping the lens with liquid stains is not good; The other is soft cloth (lens paper) with high cotton content. It is very soft and has excellent water absorption ability. It is suitable for wiping liquid stains, but it is not durable. After using it for a long time, fine fibers will fall off. It is recommended to use and change the lens paper. In addition, the lens should not be dry wiped. It should be wiped with a liquid. When wiping, the lens cleaner should be sprayed on the wiping paper first, and then the wiping paper sprayed with the cleaner should be wiped from the center of the lens to the edge.

Glass lens and glass foil
Glass lenses were lenses made of glass lenses. They had high requirements for molding technology, coating technology, precision processing, and other aspects. They had high light transmission and were not easy to age. They were mainly used in high-end imaging fields, such as single-lens reflex cameras, high-end scanner, high-end security video surveillance equipment, and so on. The glass slide was mentioned when observing meteorite slices in the rocky microscope. It was a piece of rock or meteorite that was sawed into a small rectangular shape and ground flat on one side. It was glued to a glass microscope slide with epoxy. After grinding to a thickness of 0.03 mm and sticking a cover glass, it was sandwiched between the glass slide and the cover glass. The two were different concepts that were applied to different scenarios. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Scratched lens glass
If the lens glass is scratched, you can try the following methods to repair it: 1. Cleaning and wiping: Gently wipe the surface of the lens with a clean and soft cloth to remove some minor scratches. 2. Use toothpaste: apply a small amount of non-gel toothpaste on the lens, then slowly and carefully massage it with a soft cloth or cotton swab, then wash it with water and dry it. 3. Professional repair tools: If the above methods do not work, consider using professional camera glass repair tools, which contain special chemicals and polishing materials to help remove more serious scratches. 4. Seek professional help: If self-repair fails or you don't dare to take risks, you can seek the help of professional technicians who have the experience and appropriate tools to deal with such problems. Before attempting any repairs, ensure that the relevant equipment is turned off (if applicable). For the phone camera, if you are not sure about your own repair ability, it is best to consult a professional or go to the local after-sales inspection. The after-sales address/phone number can be inquired in the device settings (For example, the phone can be inquired in the settings-General/More settings-After-sales service menu, or you can go to the official website of the after-sales service center to inquire about the address: <anno data-annotation-id ="0000008 - 4144 - 4470 - 4770 - 80000000000"></anno>.</anno>If the reversing video camera was scratched, it could be replaced directly. If the lens glass of the video surveillance camera was scratched, the glass sheet could be replaced or removed directly (but it would lose its waterproof function. To operate it, the camera shell needed to be opened). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Speckles on the lens interface glass
If there were spots on the lens interface glass, it might be dust or stains. If it was dust, when the lens was removed, the camera's light-sensitive element (CCD-based or CMOS-based) would be exposed to the air, and the dust would easily contaminate the lens interface and other parts. For dust, you can use the air blowing (ear washing ball) to blow the dust away. Pay attention to maintaining an appropriate distance and angle when blowing to avoid blowing the dust deeper into the lens. If it was a stain, he had to be extra careful when cleaning because the lens interface was an important part of the signal and power transmission between the camera and the lens. If the stain is light, you can try to wipe it gently with a clean and soft lens cloth, but don't use too much force to avoid scratching the glass. If the stain is stubborn, it is not recommended to deal with it yourself. It is best to send it to a professional camera repair shop for cleaning to avoid damage to the lens interface and affect the normal operation of the camera and lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Glass resin for camera lens
In camera lenses, glass lenses were widely used. Glass lenses had some advantages. For example, in terms of optical performance, its light transmission rate and sensitivity were higher, and its shooting ability was better in low-light environments. For example, all-glass lenses had better shooting effects at night; Its refraction index was higher, and under the same degree, it was thinner than the resin lens; Moreover, its light transmission rate and mechanical and chemical properties were better. It had a constant refraction index, stable physical and chemical properties, and was more resistant to scratching and not easy to scratch. However, there were also rumors about the use of resin lenses for camera lenses. For example, there was a saying that Canon and Nikon used plastic lenses for low-end lenses. However, according to some people's lens dismantling experience and personal understanding, they believed that there was no use of resin lenses for camera lenses. The reason was that the price of resin lenses was higher than optical glass. Glass lenses used for camera lenses could be mass produced by molds, so manufacturers did not need to use expensive and poorly reputed resin lenses (the use of resin lenses for glasses was to pursue lighter weight and anti-fall performance, but there was no such requirement for camera lenses). In the public information, only composite aspheric lenses were found to contain resin components (made of glass spherical lenses and resin sheets). However, there were also new situations. For example, the Huawei P70 series was rumored to adopt the 1MG +7P molded glass-plastic camera lens solution. Here, 1G and 7P represented the ratio of glass and plastic in the lens, and 70% of the lens was plastic. This design allowed the lens to be easily shaped into an aspheric shape and take up less space. Therefore, the camera lens used glass as the main material, and there were also new directions for the exploration of glass-resin hybrids. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Now the Lanthanide glass lens radiates
Lanthanide glass lenses were added with Lanthanum Oxides. There were dozens of radioactive neutrons of Lanthanum, but except for Lanthanum 137 and Lanthanum 138, the rest of the half-lives were generally short. Lanthanum-137 had a half-life of 60,000 years, while Lanthanum-138 had a half-life of 10.2 billion years. There was no mention of radiation protection in the description of Lanthanum glass, so it was generally safe in normal use. However, there were cases where some camera lenses containing Lanthanide glass materials were exposed to radiation due to the radioactive elements thorium-232 or Uranium-232. However, it was unscientific to talk about toxicity without considering the dose. The specific radiation value and harmfulness were not easy to accurately evaluate. Lanthanide and thorium dioxide were mainly used in the lens. The penetration power was relatively low, and the decay rate in the air was relatively fast. If it was not close to the body for a long time, it would not cause any problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Put a glass in front of the camera lens
Putting a glass in front of the camera lens could produce unexpected effects. Glass could act as a filter. If the glass was not particularly clean, the dust on it could create a hazy beauty. He could also be creative, such as sprinkling water on the glass or sticking some shiny sticker, so that the picture would show another feeling. If you want to take a portrait with a blurred background, you can use a glass as the background, with a lens of 50mm or above, and the aperture is as large as possible (such as F2.8 or larger). If you use a 70mm lens or above, the glass in the front will be blurred more completely, which can weaken the shape of the glass and avoid being exposed, but pay attention to filling the space properly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
