Beijing Zhongke Kexi Optical Laboratory Purification Project!

The cleanroom project of the Beijing Zhongke Keyi Optical Laboratory, which includes the 100-level / 1000-level precision experimental area (for electron microscope debugging / optical testing), has a cleanliness level of ISO5 (100-level). The number of particles larger than 0.5μm is less than 3520 per cubic meter. The temperature and humidity are 22℃ ± 1℃, with a humidity range of 40% – 50% RH. It features high-precision temperature and humidity control, with a pressure difference of ≥ +10Pa between the clean area and the non-clean area, and ≥ +5Pa between adjacent clean areas. It also features vibration prevention: VC-G level (meeting the 0.1μm imaging requirement for electron microscopes), with a concrete vibration reduction platform and active vibration dampers reserved. Electromagnetic shielding: low-frequency magnetic shielding walls + color steel plates, to suppress AC magnetic field interference. Noise is ≤ 50dB(A). The total construction area is 4714 square meters. The entire clean system is constructed by Beijing Aoyunfeng Mechanical and Electrical Engineering Co., Ltd.
