In order to improve the production efficiency of edible fungi, the Beijing Agricultural Technology Promotion Station has introduced seven new varieties of high-grade edible fungus, such as lotus bacteria, golden fortunate mushroom and pork belly mushroom, to conduct trial demonstrations. Among them, the lotus bacteria that have been tested in Miyun County have begun to mushroom. The largest single strain has a weight of more than 5 kilograms and the sales price is 30-40 yuan/kg. Other varieties such as Kim Fung Mushrooms are producing bacteria and it is expected that the mushrooms will be harvested in July. 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.
