Abstract

The Sun Yat-Sen University(SYSU)1.2-m Multi-Terminal Telescope is a versatile astronomical facility with three-channel photometric and low-/high-resolution spectrometric functions.The SYSU telescope comprises a Ritchey-Chretien Cassegrain bi-reflection system with a working waveband ranging from 300 to 1000 nm.Within the field-of-view(FOV)of 15′,the image quality represented in 80%encircled light energy is concentrated within 0.3 arcsec.
A Cassegrain instrument unit is mounted on a telescope derotator that enables working modes to be switched among four instruments by a central switching mirror.The equipped instruments include a three-channel photo metric terminal,a 1.25-inch visual observation terminal,a wavelength calibration unit,a long-slit spectrograph (LSS),and a fiber adaptor for high-resolution observation.Therein,the photometric terminal can perform simultaneous imaging in the b(320-450 nm),g(480-700 nm),and r(730-1000 nm)bands.By adding a set of corrective lenses,the visual observation terminal can also realize a large FOV of 0.76°.The LSS can provide high-throughput observation,with the resolution ranging from 1000 to 3000 by slit width.A high-resolution spectrograph(HRS)at the laboratory is fed by a 25-m fiber from the Cassegrain fiber adaptor.The resolution R of the HRS exceeds 30,000 to cover a wide band from 400 to 900 nm.The SYSU 1.2-m Multi-Terminal Telescope combines excellent photometric and spectrometric observational performances.The novel design of the SYSU telescope allows for a singular telescope to make contributions in both astronomical education and scientific research.
