    • PROBLEM TO BE SOLVED: To provide a thermopile type infrared sensor which can accurately perform measurement with good sensitivity by reducing an influence of infrared rays on a cold junction of a thermopile.
      SOLUTION: In a thermopile forming part, only a predetermined region containing a side of the cold junction is covered with an infrared ray-shielding layer. The infrared ray-shielding layer has a configuration being connected with a metal pedestal and a metal. Heat of the infrared ray-shielding layer is effectively dissipated. Therefore, the configuration is such that the temperature of the infrared ray-shielding layer is unlikely to propagate to the side of the cold junction and temperature rise of the cold junction can be prevented.

    • 要解决的问题:提供一种热电堆型红外传感器,其可以通过减少红外线对热电堆的冷连接点的影响而以良好的灵敏度精确地进行测量。 解决方案:在热电堆形成部分中,只有包含冷端侧的预定区域被红外线屏蔽层覆盖。 红外线屏蔽层具有与金属基座和金属连接的结构。 红外线屏蔽层的热量有效消散。 因此,这种结构使得红外线屏蔽层的温度不可能传播到冷端的一侧,并且可以防止冷连接点的温度升高。 版权所有(C)2011,JPO&INPIT
