A multi-wavelength infrared thermometer with mid-infrared temperature and spectral emissivity, which measure the target temperature and spectral emissivity of near room temperature simultaneously, is introduced in this paper. The design of the optical system and the electrical system are described in detail.The folding optical system with high image quality and large luminous flux, The blazed grating spectroscopy system can simultaneously detect the target temperature and the emissivity through the multiple mercury telluride detector line array and the electrical system. The built-in blackbody furnace and heat pipe constant temperature field diaphragm and aperture diaphragm reduce the ambient temperature drift and miscellaneous Astigmatism on the temperature measurement
