This kind of 5 in 1 laser pointer is very powerful

laser pointer has the teaching pointer function.
However, because it is actually a quantitative procurement method. So it applies to production and sales during a given period is relatively stable, thus the procurement of bulk also relatively stable materials, and for the actual production and sales in order to prevent production plan changes, changes in consumer demand or delayed delivery caused by waiting for materials or stock should also ensure that "safety stock" inventory. Therefore, the inventory of warehouse materials should be controlled between the maximum stock levels (the maximum amount of inventory = economic order quantity + safety stock) and safety stock. In this way, can effectively reduce inventory costs, product cost control and can ensure the smooth and continuous production and sales, achieve profitable growth. The flash disk transmission and single-chip machine control can be combined to design a new type of laser pointer controller. This kind of 5 in 1 laser pointer is very powerful.
Due to the adaptability, good processing quality, high precision, high efficiency, effective, multi-processing methods, pollution and other advantages of laser technology is widely used in industrial fields. Increasingly wide range of global industry recognized as the fastest growing, the application of the most important high-tech photovoltaic technology, he will become the pillar industry of the 21st century. In photovoltaic technology, one of its basic technology is the laser technology. The scientific community predicts that by 2010, information industry will be dominated by the photoelectric IT form of $ 5,000,000,000,000 industrial scale from 2010 to 2015, the optoelectronics industry may replace the traditional electronics industry. Photovoltaic technology will be renewed impetus following the microelectronic technology revolution and progress of human science and technology. The five different laser caps can create 5 types of laser picture patterns like the photo shows. 
Austrian new technology founder Dr. Gu Gongen central "thousands of plans, as well as East Lake New Technology Development Zone," 3551 Talents Scheme "to introduce high-tech entrepreneurial talent. 1982, graduated from Nanjing University of Technology and Engineering, BS in physics from 1984 to the United States studying entrepreneurship and Master of Lanka Institute of Physics, and the Connecticut State University, a master's degree in optoelectronics and doctoral qualifications. The period 1990 to 1993, Mr. Gu Gongen well-known multinational Sharp laser Sharplan Laser, Coherent laser (Coherent Laser), Heraeus Optical Company (Heraeus,) as a senior R & D engineers, R & D Director, as well as engineering and technical director and other senior positions.
