In the field of optical coating, the requirements for the vacuum environment are extremely stringent. The presence of any residual gas can negatively impact coating quality, and XIEYI cryogenic filters, with their advanced technology and superior performance, have become key equipment for creating the ultimate vacuum environment.
XIEYI cryogenic Chillers utilize advanced refrigeration technology to achieve extremely low temperatures. Their cryogenic coils can reach below -120°C, and even as low as -150°C. At such low temperatures, residual gas molecules such as water vapor and oil vapor rapidly condense on the surface of the cryogenic coils, achieving efficient capture. This efficient capture capability significantly reduces the amount of residual gas in the vacuum system, greatly shortening the vacuuming time. Compared to traditional vacuuming methods, using XIEYI cryogenic filters can shorten evacuation time by 60-90%, greatly improving production efficiency.
XIEYI cryogenic Chillers also excel in increasing vacuum levels. They can increase vacuum levels by half an order of magnitude, reaching high levels of 10⁻⁸ Torr and 10⁻⁵ Pa. A high-vacuum environment provides ideal conditions for optical coating, helping to reduce impurity contamination of the film and improve its uniformity and density. For example, in the manufacture of optical components with extremely high coating quality requirements, such as high-precision optical lenses and laser mirrors, the extreme vacuum environment created by Xieyi cryogenic equipment ensures that the coating quality reaches international advanced levels, meeting the needs of high-end applications.
Xieyi cryogenic equipment is designed with the special requirements of optical coating processes in mind. The installation position of its cryogenic coil can be flexibly adjusted according to different coating equipment and process requirements. Installing cryogenic coils between the high-pressure valve and the vacuum chamber, inside the vacuum chamber, and in the upper and lower chambers of the winding coating unit effectively addresses water vapor and oil vapor issues in different situations. Simultaneously, to prevent oil vapor backflow from the oil diffusion pump, placing the cryogenic coil at the pump inlet of the oil diffusion pump, below the high-pressure valve, not only captures the gas but also simplifies the operation process.
In terms of performance stability, Xieyi cryogenic equipment has undergone rigorous testing and verification. It uses internationally branded refrigeration compressors and environmentally friendly mixed refrigerants, resulting in rapid cooling, high efficiency, low temperature, and easy maintenance. The refrigeration system is optimized for rapid cooling and heating, achieving temperatures below -100℃ within 3 minutes, rapid defrosting and reheating within 3 minutes, and further cooling within 3 minutes. Furthermore, the equipment features multiple safety protection functions, such as alarms for excessive compressor temperature and pressure, and alarms for insufficient water cooling and excessive water temperature, ensuring stability and reliability during long-term operation.
