Nontransparent material normal spectral emissivity measurement device

The utility model discloses a nontransparent material normal spectral emissivity measurement device. Key points of the technical scheme are that: a graphite heating body is arranged in a cylindrical cavity, and is communicated with a water cooled electrode which is communicated with a direct current power supply; a semispherical water cooled flange is arranged on the top of the cylindrical cavity; observation holes are uniformly formed in the semispherical water cooled flange opposite to a groove on the top of the graphite heating body; a detector is arranged outside an observation hole on one side, and a water chopper and a reflector are arranged outside an observation hole on the other side; the detector and the water chopper are connected with a microprocessor control system through a wire respectively; the microprocessor control system is connected with a manual intelligent regulator through a wire; the manual intelligent regulator is connected with the direct current power supply through a wire; a spherical mirror is arranged outside a middle observation hole in the semispherical water cooled flange; a Fourier infrared spectrometer and a computer are assembled and matched with the spherical mirror; and a vacuumizing device is arranged on the semispherical water cooled flange. The device is high in heating speed, vacuum degree and measurement accuracy.
