HOLDER FOR TEMPERATURE ADJUSTMENT OF INFRARED SENSOR

To provide a holder for temperature adjustment of an infrared sensor, that is capable of highly accurately and stably controlling the environmental temperature of an infrared sensor using temperature adjusting air.SOLUTION: Provided is a holder 10 which accommodates an infrared sensor 1 in order to adjust a temperature of the infrared sensor 1, in controlling an environmental temperature of the infrared sensor 1 using temperature adjusting air 200. The infrared sensor 1 comprises: a lens 2 for receiving infrared rays radiated from a temperature measuring object 100; and a lens-barrel 3 for supporting the lens 2. The holder is provided with a wall part 12 which forms a ventilation surface 13 of the temperature adjusting air 200 at a position above the lens-barrel 3, and has an opening that is larger than an outer shape of the lens-barrel 3 at the ventilation surface 13, and further, forms a space S leading the temperature adjusting air 200 to the periphery of the lens-barrel 3.SELECTED DRAWING: Figure 1 【課題】温調空気によって赤外線センサの環境温度を高精度且つ安定して制御することができる赤外線センサの温調用ホルダーの提供。【解決手段】温調空気２００によって赤外線センサ１の環境温度を制御する際に、赤外線センサ１を収容する赤外線センサ１の温調用ホルダー１０であって、赤外線センサ１は、温度測定対象１００から放射される赤外線を受けるレンズ２と、レンズ２を支持する鏡筒３と、を有しており、鏡筒３よりも高い位置に温調空気２００の通風面１３を形成すると共に、通風面１３において鏡筒３の外形よりも大きく開口し、鏡筒３の周囲に温調空気２００を導く隙間Ｓを形成する壁部１２を備えている。【選択図】図１
