In recent years, Qinghai province has applied the high-quality optical observation conditions in the Cold Lake area under the strong support of the results of the project“Monitoring and leading scientific research at the Cold Lake Site of the astronomical university scientific installation”, vigorously promote the construction of the Cold Lake astronomical observation base, so far, the Cold Lake Astronomical Observation Base Telescope project has begun to take shape. 

      According to Tongmao linear motor, currently, the Cold Lake astronomical observation base has signed contracts to land nine telescope projects in seven scientific research units, and these projects are all being carried out in an orderly manner, in particular, the AIMS project of the Chinese Academy of Sciences Observatory for the accurate measurement of the sun's magnetic field has completed the installation of the main mechanical equipment of the telescope and the optical equipment of the telescope is scheduled to be installed in late July. In addition, the Tido project of the Nanjing University Time Domain Observatory has completed the construction of six observation towers and the installation of domes, the 1M telescope is being tested in Nanjing.

      When it comes to telescopes, the infrared telescope is one of the main telescopes, its successful development, expanding the scope of human observation of stars. Because of the low brightness and short wavelength of the early and late stars, it is difficult to get rid of the external interference. Therefore, it is necessary to use appropriate modulation methods to remove unwanted background interference. At present, the main mirror swing, the secondary mirror swing and the focal plane swing modulation and so on. The traditional focal plane swing modulation system generally adopts the method of rotating mirror, which is difficult to tune because of the large sweep area and the large amount of observation and interference signals entering the phase-locked device, it has been replaced by a linear motor driving the mirror to and fro in a straight line motion. 

   Kunshan has been continuously improving the efficiency and productivity of complex manufacturing processes for more than a decade. Its products, such as linear motors, linear modules, Voice Coil Motors and voice coil modules, have been highly trusted by customers at home and abroad.
