Description

Technical Field

[0001] The utility model relates to the technical field of temperature control of black body radiation sources, and in particular to a segmented precise temperature control black body radiation source device. Background Art

[0002] A blackbody radiation source device is a device that can generate and emit blackbody radiation. A blackbody is an idealized physical concept, which refers to an object that can absorb all electromagnetic radiation incident on it, neither reflect nor transmit, and emit electromagnetic radiation according to a specific frequency distribution. In reality, we can make the characteristics of certain objects close to blackbody through some specific designs.

[0003] The existing blackbody radiation source devices are usually designed to only consider the overall temperature control, without considering the precise temperature control of different regions and sections. This is mainly because the original intention of the design of these devices is to produce equipment close to the ideal blackbody radiation, and the ideal blackbody is an object with uniform temperature. Therefore, the design is more about how to make the overall temperature uniform, rather than how to achieve temperature control in different regions. However, in practical applications, we may need different temperatures in different regions to produce different blackbody radiation. For example, in the measurement of some material properties, we may need to observe the reaction of the material at different temperatures, which requires different temperatures in different regions. Therefore, it is necessary to redesign a blackbody radiation source device with precise temperature control in different sections to address the above problems. Utility Model Content
