High Precision Optical Glass Window Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
Windows at shape of round,quadrate, triangular or other polygonal are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
Specification of our optical windows as follow: High Precision Optical Glass Window,High Purity Silica Windows,Optical Round Window,Standard Optical Windows China Star Optics Technology Co.,Ltd. , https://www.realpoooptics.com

Shenyang new research and development of digital control reciprocating submersible pump sensational Daqing
Located in Xinchengzi District, Xincheng Petroleum Machinery Factory of Liuwangcun is a joint-stock enterprise established in the early 90s of last century. More than a decade, the small factory by farmer director Feng Chunguo constantly small studies, small inventions, improve new products, benefits better day by day. Feng Guochun very understanding of the difficulties in the production of oil companies, but also find the direction of business research. More than 90% of the traditional oil recovery machinery use a power plant on the ground, commonly known as "kowtow machine" of the oil machine, through the sucker rod above the oil well to lift the oil to the ground, energy consumption, supplies, land Large area, low efficiency and limited oil production. Three years ago, Feng chong-kuo whim, "If the oil power plant on the ground just fine." After several tests, he developed using the principle of magnetic levitation "rodless CNC reciprocating submersible pump" and get National utility model patents. Last December, after the ground simulation test and performance testing, the first new submersible pump was applied in Daqing Oilfield. The result is very good, yield increased by nearly 30%, daily power consumption reduced by 40% more, single well saves 47000 yuan investment.
