The LISA spectrograph (F/5) is a new single slit spectrograph in Lulin Observatory. This instrument is suitable for LOT, SLT, and even an amateur telescope in the TAOS site by connecting with a focu-reducer (or extender). The current instrumental configuration includes a 300gr./mm grating blaze and an in-built Ar/Ne arc lamp for wavelength calibration. Considering the physical dimension of the primary CCD camera (QSI 660) and applying with a 35 micron width slit, the long axis of the 2D spectrum can cover the wavelength between 400 and 850 nm with a spectral resolution of about 800. The limiting magnitude of a point source is around 16 under a 600 seconds un-binned single exposure. We had characterized this new spectrograph in late 2020 and will give a brief report in this presentation.
