<p>PURPOSE:To receive infrared rays emitted from the end surface of an infrared ray fiber with good efficiency, by downwardly curving a flat gold black on a thermopile chip in a semi-spherical shape. CONSTITUTION:A thermocouple 4 is provided on the SiO2 film 5 formed on an insulating substrate and gold black 2 is formed thereon in a film form through an Si3N4 film 3. In this constitution, a surface receiving infrared rays from the end surface of an infrared ray optical fiber 1 is formed on a semi- spherical gold black 2. By this method, the hot contact of the thermocouple 4 is provided along the surface of the gold black 2 and, therefore, the heat from the fiber 1 can be received efficiently.</p> |
