摘要	The ﬁber-fed High Resolution Spectrograph of the Chinese Xinglong 2.16-m Telescope is the main instrument for high precision spectral detection in China. In order to improve the observation performance, a wavelength calibrator based on Fabry-P´erot etalon (FPE) is developed. Here, we report on the design, transmission characteristics and vacuum thermostatic performance of the system. To meet the requirements of the calibration, the calibrator is custom-designed with the FPE gap of 5 mm, ﬁneness value of 40, and illuminating ﬁber of 100 µm in diameter, which could generate calibration lines with 30 GHz in lines space and covering 500 – 700 nm.
