All series CNI Laser modules can be fiber coupled with different core diameter MM fiber or SM fiber. You have to refer to the detailed specs of each laser modules (such as power, stability, noise, size, etc) to decide which one is suitable for your application. We would like to do the coupling job for you.
The collimator of Fiber Coupling Laser is designed to connect to the end of FC/PC or SMA905 connector and contains an AR-coated spherical lens. The distance between the spherical lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes, or to re-collimate the beam at the specific wavelength and distance of interest.

“Whole vehicle companies should come to listen to this meeting. They do not come because of the wait-and-see attitude towards the auto remanufacturing industry.†On September 6th, in a car with the theme of “circular economy and green manufacturing†On the Remanufacturing Forum (hereinafter referred to as the “Forumâ€), Guo Qimin, Director of the Department of Resource Conservation and Environmental Protection of the National Development and Reform Commission, was somewhat excited.
Guo Qimin disclosed to the outside world: “The restrictions on the raw materials for parts and components needed for automobile remanufacturing will be gradually liberalized. The government will impose two major issues on the scrapping of auto parts and scrap parts and components. No longer limit."
While opening up the raw material channels, the remaining problems of the company seem to be left only by the sales market. This is a good news for the automotive remanufacturing industry. However, in an interview with a number of remanufacturing companies, the reporter found that companies have The response to a policy is not the same, and even the wave of opposition is even higher.
An industry that has not yet emerged in China has different voices among various enterprises in the initial stage of policy liberalization.
Wait and see
On September 6th, Zhang Wei hoped to use the TEDA Forum to bring the people’s attention to the automotive remanufacturing industry again. In the conference hall that can accommodate 200 people, there were less than 50 listeners. The deserted venue made the director of the equipment maintenance and remanufacturing engineering department of the Armored Forces Engineering College and the promoter of the domestic remanufacturing industry somewhat lost.
Li Dongru, deputy secretary-general of the China Federation of Machinery Industry, told reporters, “Now there are several research institutes related to remanufacturing in China. However, the development of enterprises is not very good. Apart from several companies that insist on doing, more are Wait and see."
The reporter saw at the forum site that, apart from scholars and parts manufacturers, there was no representative of an entire vehicle company. “Before it was the policy that restricted the development of automobile remanufacturing, the barriers will soon be opened up and the enthusiasm of vehicle companies will remain low,†said Liu Jianmin, president of the China Material Recycling Association. “Wait until the policy truly opens up overseas scrapped auto parts. After the restriction, it is estimated that domestic remanufacturers, especially some vehicle companies, will strongly oppose such as fears of foreign companies monopolizing the remanufacturing industry, etc. But now these companies would rather not wait to do it, which makes people very helpless."
It is understood that China's automobile remanufacturing enterprises can be roughly divided into three categories: One is based on scientific research institutes or universities, and enters the automobile remanufacturing industry through research and practice. This part is representative of China's remanufacturing field, such as the Armored Forces Engineering College. Mechanical product remanufacturing National Engineering Center; second type is complete vehicle or engine production enterprise, relying on owning raw material and market advantages to set up remanufacturing branch company, which accounts for a large part of remanufacturing enterprises, but many Experts say that this type of company is not really investing much; the third category is the joint venture with some foreign remanufactured companies with better technology to establish new remanufacturing companies.
“Although almost all vehicle manufacturers now claim that they are investigating automotive remanufacturing technology, they are actually investing very little, and most of them are parts and components companies or remanufacturing enterprises that are joint ventures with foreign companies.†September 6, Zhang Wei told reporters, "As the government gradually recognizes the remanufacturing of automobiles, more and more companies will participate in them. However, because of the different composition of these remanufactured companies, they also have different demands in seeking policies." .
dispute
The reporter learned from the forum that there are two major barriers in China's automobile remanufacturing industry: First, China imposes mandatory scrap on the five major assemblies of scrapped automobiles; the other one is that China prohibits foreign scrapped auto parts and components from entering China. “The two bans can be said to basically block the raw material channels for China's auto remanufacturing. If there is no engine or vehicle manufacturer, it is almost impossible to develop remanufacturing technology,†said Liu Jianmin.
According to Article 14 of the State Council's Decree No. 307 “Administrative Measures for the Retirement of Scrap Vehicles†promulgated and adopted in June 2001, “Disposal of Scrap Vehicles Dismantled by Scrapped Automobile Recycling Enterprises, Five General Assembly (Automotive Engines, Steering Gear, and Transmissions) The front and rear axles and frames shall be sold as scrap metal and sold to steel companies as raw materials for smelting.†This provision allows auto remanufacturers to purchase old parts from fixed customers or auto repair markets as remanufacturing raw materials, which cannot be satisfied at all. Production and market demand have caused formal remanufacturers to get old parts difficult.
“It was exactly the desire of the auto remanufacturing enterprises for raw materials that we decided to prepare for the release of the five-year scrap limit of end-of-life vehicles.†During the meeting, Guo Qimin again emphasized to reporters: “But before the policy was officially released, No company can import or recycle scrap parts in advance, or the competent authorities will severely punish them."
However, the policy has not yet landed. When private exchanges took place at the forum, companies of different natures have already created disagreements about the release of restrictions on recycling channels.
"Let's let go of scrapped auto parts recovery, and who will guarantee the quality of recycled products? Without a systematic regulatory recovery system, releasing remanufactured recycling channels would be of no benefit to this line." Weichai Power (Weifang) Remanufacturing Limited Company general manager Li Feng told reporters.
Compared with Weichang, which has a backing engine factory, Chi Yongbo, general manager of Shanghai Xinfumei Transmission Technical Service Co., Ltd., has a different view: “How much raw materials can be provided by refueling companies and engine companies for remanufacturing each year? We can't satisfy ourselves! These remanufacturing companies rely on the survival of their parent companies. The real idea is that companies that do not have a fixed recycling channel will be able to withdraw from the market if raw materials are hard to find."
For the Development and Reform Commission revealed that it will further liberalize the planning of foreign scrapped auto parts, these companies do not buy too much between each other have a common view, that is, no benefit to China's remanufacturing industry.
"If foreign parts and components can enter the country, then foreign companies that have mastered remanufacturing advanced technology will also take the initiative. This is a harm to a new industry, and of course it is a kind of selfishness held by domestic companies," the interviewer said. The person in charge of a car remanufacturing company that did not wish to be named expressed this view to reporters: “In the past few years, several foreign advanced automobile remanufacturing companies have entered China and they hope to seize the initiative, but it is precisely because they do not have what they want. Imported raw materials from abroad are eventually forced to withdraw and seek joint venture development. If you let go, how will domestic companies survive?"
For the controversy over the post-market and recycling channel standards for remanufactured products, Cai Zhihai, deputy director of the National Engineering Research Center for Mechanical Product Remanufacturing of the Armored Forces Engineering Institute, explained that this is also a weakness of China's remanufacturing industry. The country's remanufacturing standards and system construction projects will be completed by the end of this year. It will also have to pass the effect test and when it will be announced.
prospect
Although the potential of the remanufacturing industry is large, there has been a lack of effective policy support in our country. As a chief expert advocating the development of remanufacturing, Xu Binshi has a lot of feelings.
Ten years ago, Xu Binshi, an academician of the Chinese Academy of Engineering, began to advocate the development of the remanufacturing industry and extended these technologies from the defense and military field to broader areas such as civilian use. As a leading figure in the field of military machinery, Xu Binshi, currently the director of the National Defense Key Laboratory of Armored Forces Engineering Institute's equipment remanufacturing technology, is still working in the field of scientific research. He told the Auto Business News reporter: “The tank engine will be overhauled in more than 500 hours. After 1100 hours of bench tests, the remanufactured products have the technological level, pollutant emissions, and fuel oil within the target range. The benefits are very high. obvious."
The remanufacturing of auto parts and components refers to the mass production of professionally rehabilitated used auto parts, engineering machinery, machine tools, etc. The remanufactured products achieve the same quality and performance as the original new products. Compared with manufacturing new products, remanufacturing can save energy by 60%, save materials by 70%, and save costs by 50%.
In 2010, Xu Binshi’s remanufacturing development plan submitted to the State Council was personally approved by Premier Wen Jiabao and Vice Premier Li Keqiang. In May of that year, the “Opinions on Promoting the Development of Remanufacturing Industries†issued by the ministries and commissions of the National Development and Reform Commission pointed out that in the future, pilot projects for remanufacturing auto parts will be deepened. It will focus on the remanufacturing of automotive engine parts, gearboxes, and generators, and will expand the scope of pilots to components such as transmission shafts, compressors, oil pumps, and water pumps. At the same time, the renovation of large old tires continues.
As of the end of 2010, China has formed a remanufacturing capacity of 230,000 sets of automobile engines, transmissions, steering gears and generators. Experts at that time predicted that by 2015 China's auto sales will reach 22 million, and parts and components will reach 550 billion yuan. If 5% of them use remanufactured parts, the market will reach 25.5 billion yuan.
