Recycling the lens of the mobile phone camera


Recycling mobile phone camera - Polarizing lens is a lens made according to the principle of polarization of light. It is used to remove and filter out the scattered light in the beam, so that the light can be put into the visual image of the eye on the track of the track, so that the field of view is clear and natural. Used mostly for sunglasses and camera lenses.

The role of the PL mirror is to filter the reflected light and increase the contrast of the image. It works by selectively filtering light from a certain direction. By filtering out many of the polarized light in the diffuse reflection, the intensity of the light in the sky is reduced, the sky is darkened, and the contrast between the blue sky and the white clouds is increased. When you are actually shooting, you should look at the viewfinder and rotate the front mirror. The effect of the darkest sky in the viewfinder is the most obvious. The darkest and the brightest are 90 degrees apart. You can go to any angle between the darkest and the brightest as needed.

The PL mirror can also effectively attenuate or eliminate the reflection of non-metallic surfaces. This reflected light is a typical polarized light (the reflection of the metal surface is more complicated, related to the incident wavelength and surface roughness.


The conductivity of the metal is not zero, and the reflection coefficient becomes a complex number, which causes the phase of the P and S components to change, and the reflected light becomes elliptically polarized. PL is a line offset and therefore does not contribute to metal reflected light. ), by adjusting the polarizer, it is possible to filter out the reflection of this part, thereby improving the image quality of the subject and improving the sharpness of the picture. For example, by using a polarizer, the reflection of the water surface can be attenuated, so that the fish in the water can be clearly captured. When shooting such a scene, the projection angle of the light source is close to the angle of the camera photographing, and the maximum deflection angle needs to be between 30 and 40 degrees.

When using it, you can adjust it by slowly turning the lens of the front group of the filter to minimize the reflection of the surface of the scene. In addition, the polarizer can effectively improve the saturation of the color and increase the contrast. This is because the polarizer can absorb the stray light in various directions reflected by the fog or dust in the atmosphere, so that the captured image is more pure. For example, in photography such as photographing flower stills, polarizers are often used to take colorful photos.

Futian District, Shenzhen, Yueyue Blueprint Electronic Firm is a new type of professional recycling company, mainly engaged in the recycling and supply of electronic components and electronic inventory; recycling types are: recycling camera chips , recycling mobile phone fingerprints, etc.; Shenzhen Futian The district's blueprint electronic business has its own processing factory: not only has a wide range of recycling, but also prompt delivery, abundant inventory, a fixed registered address to ensure customer reassurance and many other advantages, headquartered in Shenzhen, business coverage in Shenzhen, Dongguan, Guangzhou, Huizhou, Zhuhai, Zhongshan, Foshan, Jiangmen, Zhaoqing and other Pearl River Delta regions, Shanghai, Jiangsu, Zhejiang and other Yangtze River Delta regions, as well as the Hong Kong Special Administrative Region.


It is useful for landscape photography, floral photography, and for shooting certain scenes that are more reflective. The polarizer is used to capture the landscape and has an excellent effect on the depiction of the clouds. The refractive index of the blue sky is larger than the light scattered by the white clouds. The use of polarizers can also make the color of green leaves more saturated and eliminate the fog of urban scenes at low angles.

Polarizers are manufactured based on the principle of polarization of light. We know that when the sun is projected on the road or on the water, it directly irritates the eyes, making the eyes dazzling, tired, and incapable of lasting. Especially when you are driving a car and doing outdoor recreation, it not only affects our work and entertainment emotions, but also affects our judgment on the object and causes danger; long-term exposure to direct sunlight can cause a sharp drop in vision. Form myopia, hyperopia, astigmatism or cataracts. The special effect of the polarizer is to effectively exclude and filter out scattered light in the beam. The light can be put into the visual image of the eye on the track of the light track to make the field of vision clear and natural. Like the principle of blinds, the light is adjusted into the same direction and enters the room, naturally making the scene look soft and not glare.
