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.

[ China Agricultural Machinery Industry News ] In order to accelerate the development of water-saving agriculture and water and fertilizer integration, vigorously promote the popularization of advanced technology for weight loss and efficiency. Recently, the National Agricultural Technology Extension Service Center was jointly organized by Sinochem Agriculture, Sinochem (Yantai) Crop Nutrition Co., Ltd., Dongying Wuzhoufeng Ecological Agriculture Co., Ltd., Jixian Xiaodian Hengshan Family Farm, Shandong Soil and Fertilizer Station, Rizhao City The “New Fertilizer Technology Training Course and the National Weight Loss and Efficiency Water and Fertilizer Integration Site Meeting†hosted by the Ganxian County Agriculture Bureau and the Sinochem Agricultural Shandong Branch were successfully held in Jixian County, Rizhao City, Shandong Province.
It is understood that this meeting attracted nearly 200 new farmers, large planters and other representatives from Shandong Province to participate in training and learning. The theme of the conference was “Integration of Weight Loss and Efficiency Water and Fertilizer Integrationâ€, and the training was carried out through the three sections of Sinochem's intelligent water and fertilizer integration on-site observation, theme report and new farmer symposium. Xin Jingshu, Director of Soil and Fertilizer Division of National Agricultural Technology Extension Service Center, Wang Shuai, Assistant General Manager of Sinochem Agricultural Distribution Division, Liu Yansheng, Director of Shandong Soil and Fertilizer Station, Wu Xihua, Deputy County Magistrate of Rizhao City, Shandong Province, Shandong Branch of Sinochem Agriculture Shi Chengqi, general manager of the company, Wang Xutao, general manager of Sinochem (Yantai) Crop Nutrition Co., Ltd., Li Junliang, professor and associate dean of the College of Resources and Environment, Qingdao Agricultural University, chief designer of Sinochem Intelligent Liquid Fertilizer System, Shandong New Farmers Club Secretary-General Wang Baojie and so on attended the meeting and made a wonderful speech at the meeting.
Water and fertilizer are important material resources for agricultural production. Water is the key to fertilizer performance, and fertilizer is the key to unlocking the production efficiency of soil and water systems. Water and fertilizer integration technology refers to comprehensive regulation and integrated management of cropland water and nutrients according to crop demand, water-promoting fertilizer, fertilizer-to-water transfer, and water-fertilizer coupling.
Compared with traditional fertigation measures: water and fertilizer integration technology can improve the utilization rate of water and fertilizer, ensure the balanced supply of water and nutrients to each crop, thus saving water and fertilizer, reducing the amount of pesticides, and making agricultural products safer. Wang Baojie, the chief designer of Sinochem Intelligent Liquid Fertilizer System and the secretary-general of Shandong New Farmers Club, told reporters that taking grape as an example, the water requirement is 5-10m3/mu after water and fertilizer integration, 30% less than traditional flood irrigation. 40%; grape through the ditch backfill way to use compound fertilizer 100kg / mu, potassium fertilizer 20kg / acre, diammonium 30kg / acre, and the use of water and fertilizer integrated management mode only use liquid fertilizer 55kg / acre. The watering and fertilization of the Huishengyuan Ecological Farm requires 8 workers to finish the work in 6 days. After using the water and fertilizer integration technology, only one worker can finish the watering and fertilizing for 2 days, saving more than 90% of the labor.
The Notice of the General Office of the Ministry of Agriculture on Printing and Distributing the Implementation Plan for the Promotion of Water and Fertilizer Integration (2016-2020) pointed out that in order to vigorously develop water-saving agriculture, control the total amount of agricultural water, promote the implementation of zero growth of fertilizer use, and improve water resource utilization. Water and fertilizer integration is the only way to ensure national food security, develop modern water-saving agriculture, transform agricultural development methods, and promote sustainable agricultural development.
At the on-site meeting, Professor Li Junliang from the College of Resources and Environment of Qingdao Agricultural University fully recognized the water and fertilizer integration technology of Sinochem Agriculture. He said that water directly transports the water and fertilizer required by the crop to the root soil through the micro-irrigation system, which can fully guarantee the effective supply of nutrients, water and the rapid absorption of roots. While increasing the utilization rate of fertilizers and water, it also saves a lot of labor, especially in greenhouse cultivation and large-scale operation.
Xin Jingshu, Director of the Soil and Fertilizer Technology Department of the National Agricultural Technology Center, reviewed the major achievements in the development of the soil and fertilizer industry in recent years, profoundly expounded the main problems of chemical fertilizer application in China at the present stage, and put forward the idea of ​​jointly promoting the reduction and increase of fertilizers.
Shi Chengqi, general manager of Sinochem Agriculture Shandong Branch, said that Sinochem Agriculture adheres to the vision of creating beautiful agriculture through science and technology, is committed to relying on core technology, adhering to the conscience of the industry, realizing planting and agricultural safety, and always focusing on making modern agriculture more sustainable, and farmers are more Abundance, a better mission for agriculture, a series of service work, Shandong Branch will be up and down, work hard, serve new subjects, serve partners, and provide full planting solutions.
Wang Shuai, assistant general manager of Sinochem Agricultural Distribution Division, said that in the future, Sinochem Agriculture will continue to increase investment in water and fertilizer integration application technology and agricultural technology service capabilities, and increase the promotion of this technology nationwide. Training and technical guidance for new professional farmers around cash crops. It is planned to build 500 intelligent liquid fertilizer stations in 2018.
