A brand new kind of mid infrared multi wavelength radiation thermometer for the measurement of true temperature and emissivity near room temperature with high signal to noise ratio (SNR) was presented. By applying blazed grating and refractive reflected optical system with high image quality and throughput, the temperature and emissivity were available simultaneously by the MCT semiconductor sensor array and electric system. Inner blackbody source was installed to compensate the surrounding temperature drift, and the temperature of field stop and aperture stop was controlled by a heat pipe to reduce the influence of stray radiation on temperature measurement. The main structures of optical and electric systems were described in detail.
