This lens is made of curve shape, not sphere. The aspherical lens has surface, shown in parabolic surface and polynomial expression. Ellipsoid, hyperboloid, fourth curved surface are examples,Aspherical lenses are designed to reduce spherical aberration
aspheres, are available molded, CNC-polished, or MRF-polished, either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations, We could provide plano convex aspheric lens, plano concave aspheric lens, double convex(biconvex)aspheric lens
Cylindrical Convex Aspheric Lens,Spherical Convex Aspheric Lens,Meniscus Aspheric Lens,Glued Aspheric lens,Achromatic Aspheric lens Changchun Ruiqi Optoelectronics Co.,Ltd , https://www.ruiqi-optics.com
Five transformations in the transformation and upgrading of the manufacturing industry
China is now the world's largest manufacturing country, but it is not a manufacturing power. In the process of moving from a big country to a strong country, transformation and upgrading is the only way for China's manufacturing industry. At the national level, this is the era of high-quality development and historical mission. An open and fair market economy system is particularly important. And specific to the enterprise, transformation and upgrading is the choice of different development paths. The choice is painful. Entrepreneurial change must first change its own life. The process of enterprise transformation and upgrading is the process of transformation and rebirth. In this process, the entrepreneur's vision is to look outward and accurately to see the changes and trends of the new era environment, but also to inwardly re-examine the company's own advantages and core competitiveness. There are five barriers that must be overcome. The first barrier is the market barrier. In particular, private enterprises will encounter more difficulties in their development. For example, old problems such as difficulty in handling, difficulty in financing, and difficulty in implementing policies have not been effectively resolved. How to use the "subtraction" of government power in exchange for the "addition" of market vitality? One of the most important points is to break down market barriers. Let enterprises, as market players, carry out benign competition in the same open and fair market environment, learn from each other's strengths and complement each other, and the transformation and upgrading of manufacturing industry will have the cornerstone and guarantee. The second pass is inertial thinking. The bigger the business, the greater the success, the greater the inertia. Such companies often overlook the fact that relying on past success may mean today's failure. Today's world is a world of cross-border competition. It is not Kodak that beats Lekai film, but the industry has been subverted by digital images. In the future, more and more industries will wither or even disappear. This warns us to break the inertia thinking and re-examine our own advantages and core competitiveness with a cross-border perspective to find new growth directions. The third pass is Xiao Fu. Many enterprises feel that the cost of transformation and upgrading is high, the burden is heavy, and the risks are high. They often choose not to turn and do not turn, and they can maintain as much as possible. Many manufacturing industries are doing OEM production. Although the profits of 2/3 of the products are taken away by the brand owners, when there is no crisis of survival, many companies would rather see the meager profits in front of them than to take risks. "I want to transform and upgrade" is a problem that enterprises need to solve. In addition to the government's need to support the development of new kinetic energy, enterprises themselves must overcome the inertia of "the ship is not well turned" and the confusion of "transition to find death, not transformation and other death." The fourth pass is the ability to innovate. Most of China's manufacturing industry is at the low end of the industrial chain. Starting from low-end products and developing high-end products, this is a difficult road to innovation. Intellectual property accumulated by innovation is an important weapon for enterprises to participate in competition. Our protection of intellectual property rights is far from enough, which affects the enthusiasm of enterprise innovation. China's current invention patent application acceptance is the largest in the world, but the maximum compensation for a patent infringement is only 1 million yuan, far lower than the developed countries. If the case is bigger, the money is not enough to pay legal fees. At the same time, the lack of investment in enterprise innovation and the lack of talent also restrict the independent innovation capability of enterprises. The fifth pass is the level of integration. The integration of manufacturing and service industries, the integration of manufacturing and information technology has become a major trend in the transformation and upgrading of manufacturing. Businesses may have only sold products before, and may now sell services. At present, the traditional manufacturing of American General Motors only accounts for about 30% of the total output value, and 70% of the business is composed of "technology + management + service" associated with its manufacturing industry. In the process of promoting transformation and upgrading, a new generation of information technology provides a strong technical foundation. Especially after the commercialization of 5G networks, a decentralized Internet of Everything will come. The Internet of Things can connect the upstream and downstream of the supply chain at a lower cost, forming a real-time collaborative supply chain that connects the end customers of the market, the various departments within the manufacturing industry, and the upstream and downstream parties. This will greatly enhance the competition in traditional manufacturing. force. For the traditional manufacturing industry, the service industry and informatization are all areas that require deep learning, and it is also doomed to the difficulty of integration. The manufacturing industry is facing unprecedented challenges and faces unprecedented opportunities. Today's entrepreneurs can only overcome the difficulties and overcome the difficulties. The transformation and upgrading of China's manufacturing industry can “kill a bloody road†and achieve high-quality development.
