Assemblement and adjustment of mechanical and optical sysytem for 1 M infrared solar telescope has been finished in Yunnan Observatoy。

Main body of 1 M infrared solar telescope was undertaken by NIAOT。

Main optical system of the telescope is modified J.Gregory with F/45.9。

The telescope has high luminous flux、low polarization 、diffraction limited resolution and wide spectra coverage from near violet to near infrared。

The telescope is equipped with high precision polarizing analyzer、multi-waveband spectrograph、large dispersed spectrograph and multi-channel filter。

Testing result for the telescope listed below：

1)：system wave aberration better than 1/9 wavelength；

2)：system resolution reach 0.2 arcsec；

3)：vacuum limited for vacuum system less than 8 Pa；

The telescope was turned over Yunnan Observatoy for fine adjusting on August 1，2010，which will start trial observation。
