In recent years, a number of astronomical telescope projects have been“Settled” in the cold lake of Qinghai in our country. 

    These include the 50BiN telescope, which was launched in December 2020 as a China West Normal University for scientific observations, and the PAST and Tintin telescopes of the Institute of Geology and Geophysics of the Chinese Academy of Sciences, which were partially 2021 in October 2020 The Song Telescope Project of the China Observatory, the mid-infrared Observation System Project for the accurate measurement of the Sun's magnetic field, and the Purple Mountain Observatory multi-application Survey Telescope Array have been completed The TiDO project of the time-domain Observatory and the wide-field spectroscopic survey telescope of Tsinghua University are among the Nanjing University to be built in 2022. And the reason why they are all clustered together in the cold lake to“Settle down”, according to the small series of linear motors in Tongmao, is because the monitoring results for many years show that, the key monitoring data needed for optical astronomical observation, such as visibility and clear night time, performed well in the Saishtun mountain region of the Cold Lake.

      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large sweep area and the large amount of observation and interference signals entering the phase-locked device, it has been replaced by a linear motor driving the mirror to and fro in a straight line motion.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.
