We have developed a Wide Field Cryogenic Telescope II (WFCT-II), which contains a whole telescope-optics in a cryostat to suppress thermal emission from the whole telescope. The cryostat is of a cylindrical shape of 800 mm length and 300 mm diameter. The telescope inside is a Ritchey-Chretien system with the primary mirror of 231 mm in diameter and a focal length of 1500 mm. The InSb 1k × 1k infrared array detector (Aladdin II) has a FoV of 1 square degree and a resolution of 3'' × 3''/pixel. We can install 5 filters whose wavelengths range from 1 μm to 5 μm.
