The resolution of the camera can reach a million levels, but if the lens with which it is matched does not match it, it will not be able to fully exhibit the camera's ultra-high resolution effect. At present, there are many Japanese lens manufacturers, with their own technical advantages, dedicated to the development of high-definition lenses, and launched a series of million HD cameras corresponding to the lens. From the results of this test, the lens product not only has a great improvement in the structure of the process, but also in terms of clarity, light transmittance have also been greatly improved.
The first is the use of aspherical lenses. When the light is incident, the aspherical lens allows the light energy to be focused on one point, eliminating aberrations, and is therefore most advantageous for producing large apertures, high magnification zooming, and extremely wide-angle short-focus, telephoto telephoto lenses. While improving the picture quality, the size of the lens body can be greatly reduced, and the volume of the lens can be reduced. At the same time, the imaging accuracy, light transmittance, and color reproduction are more accurate. In addition, the low-scattering lens has the characteristics of non-parallel optical imaging, which can effectively eliminate the color difference phenomenon that causes the contrast and sharpness of the image to be weakened. Therefore, there are now manufacturers who have organically combined the aspherical lens and the low-scattering lens to effectively improve the image quality. The resolution of the lens, especially the sharpness of the edge image. In fact, the improvement of the sharpness of this edge image can be confirmed from the lens of this test.
The second is the infrared lens. In the face of more and more places that require all-weather monitoring, infrared cameras have become another growth point for each brand's shot for market share. The IR lens adopts the latest optical design, special optical glass materials and special coating technology, which can eliminate the problem of focal plane offset of visible light and infrared light, and the image is still clear in the infrared light environment. In addition, in order to increase the transmittance of infrared light, IR lens will use multi-layer coating technology. In this way, infrared corresponding sharpness imaging can be fully realized, so that light from the visible light to the infrared light area can be imaged on the same focal plane. However, at present, the shipment of IR lenses is not particularly large. Of course, there are many factors, and we will not discuss them here.
On the other hand, from the perspective of the market, Japanese lens manufacturers have mastered advanced technologies and have occupied a certain market share in many high-end fields, such as the Shanghai World Expo, etc., and they have been continuously understanding the Chinese market, based on the local market, and providing local services. . Of course, although there are partial differences between domestic brands and imported brands, it is believed that in the future, the gap will be gradually narrowed and a breakthrough will be made.
